What Does Error Code E22 Mean on a Bosch Dishwasher?

Residual water in the sump — filter or impeller area blocked.

E22 fires when the control board completes the drain step but still senses water in the sump, meaning the last of the water never reached the pump. It typically points to a clogged filter or debris blocking the impeller area rather than the pump itself failing to move water. This distinguishes it from E24 and E25, which trigger during draining from a blocked hose or restricted flow, not leftover water after the cycle ends.

Models affected: Bosch dishwashers with a self-cleaning filter and cylindrical sump filter, including models such as SHEM63W55N, SHPM65Z55N, SHXM4AY55N, SHEM3AY55N, SHP878ZD5N, and SHX878ZD5N
What owners report: Owners commonly report standing water in the filter well after every cycle, and the fix is frequently as simple as twisting out and rinsing a neglected filter. It can appear more often after washing dishes with heavy food debris or broken glass, and a false-seeming trigger sometimes clears once the impeller cover is popped off and cleared.

Frequently Asked Questions

Can I keep using my Bosch Dishwasher when error E22 appears? +
You often can for a cycle or two, but the drainage issue behind E22 will keep interrupting normal operation until it is fixed. Plan the repair rather than ignoring the code.
What most commonly causes E22 on a Bosch Dishwasher? +
Across reported Bosch dishwasher repairs, the most frequent is filter unit clogged with food debris (50% of cases), impeller cover area blocked (glass shards, fruit pits) (30%), then drain pump weak or partially jammed (20%). Check them in that order before replacing any parts.
E22 keeps coming back after a reset — what should I check next? +
A reset only clears the stored E22 fault; if it returns, the drainage problem is still present. Move on to the physical checks — clean the filter unit, then clear the pump well — since the code will reappear until the root cause is resolved. This is a beginner-friendly job needing only basic hand tools.
How much does it cost to fix Bosch Dishwasher error E22? +
A DIY repair typically runs $0–$15 in parts, versus $120–$230 for a professional service call, so handling it yourself saves around $120. Expect the work to take about 10–20 minutes.
Which Bosch Dishwasher models show error E22? +
E22 is documented on Bosch dishwashers with a self-cleaning filter and cylindrical sump filter, including models such as SHEM63W55N, SHPM65Z55N, SHXM4AY55N, SHEM3AY55N, SHP878ZD5N, and SHX878ZD5N. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
