Bosch Dishwasher Repair by Insured Denver Technicians

Bosch Dishwasher Repair Across the Denver Metro Area

Bosch currently lists 58 dishwasher models in the US, and they do not all report a fault the same way. What your machine can tell us depends on which series it is. We repair all of them across Denver and the surrounding metro.

What Your Bosch Can Tell Us Depends on Its Series

The ladder runs 100, 100 Plus, 300, 500, 800 and Benchmark. The step that matters most on a repair call is not the wash system. It is whether the panel can show you a fault code at all.

Bosch’s own 100 Series manual has no numeric codes in its troubleshooting table. A blocked drain, a plug left in a new garbage disposal and a closed supply valve all raise one indication. Four vertical LEDs light at once, and the panel cannot narrow it further.

An 800 Series or Benchmark shows E:61-02 on a display instead, and the cause narrows to one path. That single difference decides how much we can settle by phone before a technician drives out.

• 100 Series: no third rack, and fault reporting by LED pattern only
• 300 Series: standard third rack, PureDry condensation drying, no zeolite chamber
• 500 Series: AutoAir door release on six of eight models, PureDry on the other two
• 800 Series: 18 models, CrystalDry drying, flexible third rack on the full-height ones
• Benchmark: three models, ball-bearing rack glides, and a built-in water softener on all three

FlexSpace tines get misread constantly. They are fold-down lower-rack tines, called flip tines in the manual, and only eight models have them. Those eight are scattered across the 300, 500 and 800 Series.

Zeolite Codes Belong to 800 Series and Benchmark Hardware

Four codes on Bosch’s error-code page name the zeolite container outright: E07, E10, E2120 and E2130. A machine can only raise them if it has that container. Bosch’s own spec tables say which machines do.

CrystalDry appears on exactly 21 of the 58 US models. That is all 18 of the 800 Series and all three Benchmark models, and nothing below them.

The whole 500 Series is out too. Six of its eight models dry with AutoAir and the other two use PureDry, so no 500 Series has a zeolite chamber. Bosch’s owner guide for the 100, 300 and 500 Series never mentions zeolite, CrystalDry, salt or a softener.

One trap inside Bosch’s own list is worth knowing. E07 carries the same published text as E2130, and E10 carries the same text as E2120. The pairs invert, so anyone matching short codes to long codes in order gets these two backwards.

• Naming

  Bosch calls it CrystalDry, Crystal Dry or Zeolite across its own documents

• Burn risk

  Bosch warns that the zeolite container outlet gets hot, so never touch it

• Series

  Only the 800 Series and Benchmark carry the hardware these four codes describe

Two Bosch Documents Disagree About E:21-30

Bosch publishes two different causes for the same zeolite code, and the gap decides whether you buy a part.

One Bosch document sends you to a motor. The other sends you to move a plate. Only one of those is free to try.

We check the loading first on any 800 Series or Benchmark showing that code. The same manual tells owners to keep dishware clear of the zeolite intake and outlet openings.

A technician who has read only the web page will quote a fan motor. Reading both Bosch sources first is what keeps that off your invoice.

Three Code Formats, and Bosch Never Prints Them Side by Side

Bosch writes dishwasher faults in three shapes, and each shape lives in a different Bosch document.

• Short, such as E22 or E24, on Bosch’s error-code page
• Long, such as E9240 or E6102, on that same page
• Colon and hyphen, such as E:92-40, on the display and in the owner manuals

Bosch never prints all three together and never states that one equals another. So read us the exact string on your panel, punctuation included. Guessing the translation is how a diagnosis goes wrong before anyone opens the door.

Two entries exist in one place only. E:92-10, a lower spray arm not correctly fitted, appears in the 800 Series manual and has no counterpart on the web page. E:61-60 reads as a PowerControl spray arm reference fault on the web page, and as a bare technical error in the manual.

PowerControl sits on 12 of the 58 models: all three Benchmark and nine of the 18 800 Series machines. The standard 800 manual lists E:61-60 and E:92-10. The ADA-height 800 machines have no PowerControl arm, and their manual carries a shorter table without either code.

Bosch Code Scan Strip and When It Becomes Our Job

Each row names the string, the Bosch document it comes from, and which machines can show it. Bosch publishes no per-code series list, so the series column is read from the hardware each code names. Its US page also carries no E08, E11, E13 or E26, so a code in that shape did not come off Bosch’s list.

Two of these already have full answers on our site, and this page will not repeat them. Our Bosch E15 guide covers the leak-protection trip. Our not-draining guide walks the filter, the pump cover and the hose.

Read those first, then book a visit if the code comes back.

AutoAir Not Working Is Usually the Cabinetry

AutoAir is a 500 Series feature on six models. It releases the door at the end of drying to let fresh air in. When it stops working, every cause Bosch publishes is about the install or the door, not a failed part.

• The dishwasher is not installed level
• Cabinetry or countertop leaves the door no clearance to open
• A cabinet screw or piece of hardware is touching the door
• Sticky door seals are holding the door shut
• The pitch of the machine needs a slight forward lean

This lands hardest in remodelled Denver kitchens. A tight panel install can stop AutoAir without a single part failing. We have seen a new countertop leave the door no clearance to open. To the owner it reads as a broken drying cycle.

A Flashing InfoLight and a Missing One Are Different Signals

InfoLight projects a beam onto the floor so you know a quiet machine is running. Bosch lists it on 31 of the 58 models, all top-control or fully integrated. Front-control models have a visible panel instead and do not carry it.

A flashing beam is a published signal. Bosch’s manual says it means the door is not completely closed, which points straight at the latch, the lock and the micro switch.

A missing beam is not evidence of a fault by itself. Bosch publishes three innocent reasons for it.

1. The owner switched InfoLight off at basic setting I:00
2. The machine sits flush at eye level, so the beam is not visible
3. The program has ended, which is exactly when the beam goes out

A dark floor on its own is not evidence of a failed control board, and Bosch publishes no such link. TimeLight, which projects the time remaining, is a separate feature on four models.

ADA-Height SG and 18-Inch SP Bosch Dishwashers Fit Differently

Most Bosch dishwashers stand 33 7/8 inches tall. The SG platform is 24 inches wide at 32 1/16 inches tall, and the SP platform is 17 5/8 inches wide at that same height. Bosch files both under one category.

• All four SG models carry a built-in water softener
• None of the four SP models carry one
• An ADA 800 takes the standard third rack, not the flexible one
• An ADA 800 has no PowerControl spray arm and a shorter fault table
• The 18-inch 800 models run 44 dBA against 42 on the full-size machines

Same short height, opposite answer on the salt dispenser. An ADA 800 is not a full-height 800 with the legs wound down, and the manual Bosch ships with it says so.

Fit matters on a service call. The cutout for a standard 24-inch model is 33 7/8 by 24 by 24 inches. A short machine cannot back-fill that opening without filler, and outlet hose lengths vary across the range.

AquaStop closes the inlet and runs the drain pump when it senses a leak, even with nobody home. AquaStop Plus adds a second hose around the inlet hose on five models. Bosch publishes no reset for either, so a trip means shut the water off and call.

Denver Water and Aurora Water Are Not the Same Number

Denver Water’s 2025 report puts average hardness at 89 mg/L, with a range of 48 to 116. That converts to roughly 5.2 grains per gallon. Aurora Water publishes 136 ppm, ranging from 87 to 198.

Bosch prints its own hardness bands, H00 through H07, on a mmol/L scale. Convert Denver Water’s average onto that scale and it lands in H00, the softest band. There Bosch says you do not need dishwasher salt. Aurora’s average converts to H01, and its published peak reaches H03.

So the Metro is not one number, and which utility serves your street changes the answer. We do not extrapolate either figure to districts drawing on Denver Basin groundwater, because they publish their own.

The hardware answer is just as split. Nine of the 58 models have a built-in softener.

• All three Benchmark models carry one
• All four ADA-height models carry one
• Two other 24-inch models carry one
• No 18-inch model does, and neither does the ordinary 24-inch Bosch

For cloudy glassware, Bosch’s own published remedies point elsewhere first: rinse aid dosing, detergent choice, a dirty filter or a scaled spray arm. The genuine limescale code is E12, and Bosch’s remedy for it is to descale the machine. Bosch also asks that a dishwasher be winterized by a professional if a house sits empty through freezing weather.

When to Call Wilson & Myers

Some of this you can settle yourself in ten minutes, and we would rather you did. Work through these before you book anything.

1. Write down the exact string on the panel, colon and hyphen included
2. Clean the filter in the sump and check the drain hose high loop
3. On a new garbage disposal, confirm the installer removed the knockout plug
4. On an 800 Series or Benchmark, move dishware clear of the zeolite intake
5. If the InfoLight is flashing, push the door until the latch fully engages

Past that point it becomes ours. Bosch routes the door latch, the door lock, the micro switch and the hinges to a professional for safety reasons. A tripped leak-protection system is the same call, because no reset exists to try.

Our technicians are insured and work across the Denver Metro Area. We diagnose first and quote second, and you decide before any part is ordered. Book a Bosch dishwasher repair and tell us the code you wrote down.

Bosch Dishwasher Repair FAQ

The questions Denver Metro owners ask us most, answered from Bosch’s own documents rather than from the repair forums.

What does E24 mean on a Bosch dishwasher?

Bosch’s error-code page puts E24 on the drain path: a loose drain pump cover, a kinked hose or a blocked air gap. Our not-draining guide covers those checks in order.

What does E15 mean on a Bosch dishwasher?

The safety switch has found water in the base and the leak protection has tripped. Bosch’s instruction is to turn off the water inflow and contact support. Our Bosch E15 guide explains the rest.

What does E25 mean on a Bosch dishwasher?

Bosch’s error-code page lists E25 with the drain family. Its 800 Series manual carries E:61-03, which names a still-plugged garbage disposal, a kinked drain hose or a missing high loop.

Why will my Bosch dishwasher not start?

Bosch names the door latch, the door lock and the micro switch first, and routes all three to a professional. A house supply voltage that is too low raises E27, which is an electrician’s job rather than ours.

Why is my Bosch dishwasher blinking or beeping?

On a 100 Series that is the only fault language the panel has. Four vertical LEDs lit together cover several unrelated causes at once, so the machine cannot tell you which one applies.

Do I need a water softener for a Bosch dishwasher in Denver?

Convert Denver Water’s published average onto Bosch’s hardness scale and it lands in the softest band. There Bosch says salt is not needed. Aurora Water’s figures sit higher, so the answer depends on your utility.

How much does Bosch dishwasher repair cost?

We diagnose first and quote second, and you decide before any part is ordered.

How long does a Bosch dishwasher last?

Bosch publishes no service life, and the figures circulating online are unsourced. What Bosch does commit to is spare parts for up to 15 years from the date a model reached the market.

Which Denver Metro areas do you cover for Bosch dishwasher repair?

We work across Denver, Aurora, Lakewood and Centennial, plus the rest of the Denver Metro Area. Every repair carries a 100-day labor warranty, and we source Bosch parts through national supplier networks and manufacturer contracts.
