How to Reset Your Bosch Dishwasher and Decode Pesky Error Messages

Nothing kills the post-dinner buzz faster than opening your Bosch dishwasher and finding a cryptic error code blinking back at you from a pool of dirty water.

Your Dishwasher’s Secret Language: Understanding Error Codes

Modern dishwashers are brilliant, but sometimes they act like dramatic performers. They don’t just break; they flash a secret code to tell you exactly what’s wrong. Understanding these codes is the first step to a quick fix. Bosch’s built-in diagnostic system throws these codes to flag specific issues, and the good news is, a simple reset often solves the problem. But when it doesn’t, the code is your guidebook to the next step.

It’s like your kitchen’s hardest worker is sending you a text message. A little puzzling at first, but a lifesaver once you know how to read it.

The Universal Fix: How to Perform a Soft Reset

For a dishwasher that’s stuck, not draining properly, or showing a temporary glitch, a soft reset is your go-to move. It’s the gentle reboot that clears minor errors without a full power cycle.

Step 1: Open the Door and Press. Open your dishwasher door to access the control panel. Find the Start/Reset button (on some models, this is the same button and may be labeled “Reset 3 Sec”). Press and hold it for 3 to 5 seconds until the display changes (often to 0:00 or 0:01) or you hear the drain pump kick on.

Step 2: Let It Drain. Close the dishwasher door and let it run its drain cycle for about a minute to clear any standing water.

Step 3: Restart Fresh. Open the door again, press the On/Off button to power the unit down and then back on. This completes the reset, and you can now select a new cycle.

Some Bosch models have specific “Cancel Drain” buttons. If you see two buttons with dots under them on either side of a center button, press and hold both for 3-5 seconds to reset.

“A quick reset can be the difference between a five-minute fix and a frustrating afternoon. It’s always the best place to start.”

The Power Cycle: When You Need a Hard Reset

If the soft reset didn’t work or the control panel is completely unresponsive, it’s time for a hard reset (or power cycle). This cuts all power to the dishwasher’s brain, forcing it to forget any problematic commands.

Option 1: The Plug. Safely pull your dishwasher out from the wall just enough to unplug it from the electrical outlet. Wait 1 to 2 minutes to ensure the internal components fully discharge, then plug it back in.

Option 2: The Breaker. Can’t reach the plug? Head to your home’s main circuit breaker panel. Find and flip the breaker that controls your dishwasher to the “Off” position. Wait for 2 to 3 minutes, then flip it back to “On”.

After either method, turn your dishwasher back on at its control panel. A hard reset returns the appliance to its default state and clears most persistent electronic glitches.

Decoding the Message: Common Bosch Error Code Solutions

A reset doesn’t always make the code go away for good. If it comes back, here’s what some of the most common Bosch error codes mean and what to do next.

E15 – Leak Detection / Water in Base: This serious code means the leak protection system has been triggered. First, turn off the water supply to the dishwasher at the shut-off valve under your sink. Check for visible leaks or water on the floor. Sometimes, a small spill can trigger it by mistake. Tilt the dishwasher gently to drain any errant water, then perform a hard reset. If the code returns or you find a leak, professional repair is needed.

E22, E24, E25 – Drainage Issues: This family of codes points to a clog or pump problem. E22 specifically means a clogged filter. Your first move for any of these should be to remove, clean, and reinstall the main filter. For E24/E25, also check that the drain hose isn’t kinked and that the drain pump cover under the filter is secure. Clearing a physical blockage often resolves the issue.

E12 / E2060 – Limescale Buildup: Common in hard water areas, this code signals mineral buildup in the system. The official fix is to run an empty cycle using a Bosch Dishwasher Descaler or a cup of white vinegar on the top rack. To prevent it, use softening salt if your model has a built-in water softener.

E16, E17, E18 – Water Fill Problems: These indicate the dishwasher isn’t getting enough water. Check that the household water supply valve is fully open and that the inlet hose under the sink is not kinked. Ensure the water flow rate is adequate (at least 10 liters per minute).

E01, E02, E05, E06, etc. (Most “E0-” Codes): Many codes starting with E0 indicate an electronic fault on the main control board or with a sensor. For these, Bosch’s standard advice is to first perform a hard reset at the circuit breaker for 30 seconds. If the code returns immediately after resetting, it typically requires professional diagnosis and repair.

Your Bosch Dishwasher Reset & Error Code FAQ

I held the Start button, but nothing happened. What now?
Move straight to a hard reset by unplugging the dishwasher or flipping its circuit breaker for a few minutes. This overrides any unresponsive controls.

Is it safe to reset my dishwasher often?
Occasionally resetting it is perfectly safe for the appliance. However, if you find yourself needing to reset it constantly to clear the same error, that’s a sign of an underlying problem that needs professional attention.

Will unplugging the dishwasher clear an error code?
A hard reset (unplugging or using the breaker) will clear the code from the display. However, if the fault that caused the code still exists—like a physical clog or broken part—the code will simply reappear once you restart a cycle.

What if my error code isn’t listed here?
First, find your exact dishwasher model number (usually on the interior door frame) and consult your owner’s manual. For the most authoritative list, visit the official Bosch Dishwasher Error Codes page. If you’re still stuck, Bosch Customer Support can help.

When should I absolutely call a professional?
Call for help if you see recurring codes after a reset (especially control board errors like E01-E04), any code indicating a leak (E15), or if you are uncomfortable checking electrical components or disassembling parts to access the drain pump.
