Bosch Dishwasher Error Code E22: Meaning and Fix
Reading the dishwasher display
A dishwasher reports its fault in the display window, or by blinking a cycle light a set number of times with a pause between groups. Count the blinks and pauses before opening the door. Bosch shows the code with a leading E and a number on both dishwashers and washers.
Bosch (part of BSH Home Appliances) uses E-numbered codes on dishwashers and washers. Its dishwashers share control platforms with Thermador and Gaggenau, so the same fault can appear on those brands. The codes apply to model numbers such as SHPM65Z55N, SHE53T55UC and WAT28400UC; check the label on your unit to confirm yours.
What causes E22
- Food scraps, lint, coins or other debris blocking the drain pump, filter or hose
- A kinked, crushed or clogged drain hose or standpipe, or a disposal knockout plug that was never removed
- Grease build-up on the filter mesh
- A weak, jammed or burned-out drain pump motor
How to fix it
- Stop the cycle, switch the appliance off and unplug it (or flip its breaker) before touching anything.
- Bail out standing water with a cup and towel, then clean the filter or pump cover and remove anything that does not belong.
- Soak the filters in hot water with dish soap and scrub them with a soft brush.
- Check the drain hose from the machine to the sink or standpipe for kinks, crush points and clogs; straighten or flush it with warm water.
- Look for a disposal knockout plug or a drain loop that sits too low, which can siphon or block flow.
- Restore power and run a short drain or rinse cycle; if the pump hums but does not move water, replace the drain pump.

Questions
What does error E22 mean on a Bosch dishwasher?
The dishwasher noticed that water was not leaving fast enough, which is usually a blocked filter. Exact behavior can vary by model and software version; confirm against your own manual.
Can I keep using my dishwasher while E22 is showing?
Not really. Water that stays in the machine smells, breeds bacteria and keeps the code coming back, so clear the drain path first.
How do I clear E22, and can I fix it myself?
Cancel the program, switch the appliance off and leave it unplugged (or the breaker off) for about five minutes, then restart. The code only stays cleared if the underlying problem is fixed, so work through the steps above. This one is usually a do-it-yourself job with basic tools.
