Bosch Dishwasher Not Draining 300 / 500 / 800 / Benchmark — Standing Water Fix
Bosch dishwashers (300, 500, 800, Benchmark — SHE / SHX / SHP / SHE models) handle drain failures differently than American brands: there's a removable drain pump cover under the bottom filter, a check valve that's a known wear part, and the controller usually throws E24 or E25 to tell you exactly which one. Below: how to diagnose Bosch-style and what the repair costs in the Twin Cities.

What we fix in Minneapolis
The Minneapolis repair mix
Filter + screen + drain pump cover — the Bosch sequence
Bosch designed the bottom of the tub for service: unscrew the cylinder filter, lift the flat metal screen, then twist off the white plastic drain pump cover (a small arrow shows direction). Underneath the pump cover is the impeller — clear any glass shards, olive pits, or bits of label that wrapped around the blades. If you reinstall the cover wrong, you get an immediate E24 — make sure it clicks fully into position.
E24 vs E25 — what each code means
E24 = drain pump cover removed, dislodged, or blocked. Almost always a service-trip fault (cover not seated after cleaning) or a clog. E25 = drain pump current draw out of spec, or the check valve stuck closed. We diagnose E25 with a current-draw test at the pump connector; if pump is good, the check valve has failed.
Check valve — Bosch-specific wear part
The check valve at the top of the drain pump prevents back-siphon from the sink drain. By year 5–7 the rubber flapper fails or the valve seat warps, and the dishwasher either fails to drain (stuck closed) or floods at fill (stuck open). $185–$245 OEM installed. We always inspect during any drain-related call.
Drain pump replacement
When the pump itself has failed (no current draw, seized impeller, burned motor), it's a full pump-and-housing swap. Bosch pumps are quick-disconnect once the kickplate is off. $285–$385 OEM installed.
Hose loop, air gap, and disposal knockout
Bosch in the U.S. uses a high-loop drain (under the sink) — confirm the hose rises to a high point before dropping into the disposal or air gap. On new installs paired with a new disposal, the knockout plug must be punched out — common miss that creates immediate 'won't drain' calls.

FAQ
Minneapolis questions, answered
Why is there standing water in my Bosch dishwasher?
5 causes in order: clogged filter, debris under the metal screen, obstruction in the drain pump impeller (cover comes off), failed check valve, or failed drain pump. We diagnose in that order to avoid replacing the wrong part.
What does E24 mean on a Bosch dishwasher?
Drain pump cover dislodged, mis-seated, or obstructed. Pop the white cover under the filter housing, clear any debris, click it firmly back into position. If E24 returns after a proper reseat, the cover seal has failed and needs replacement.
What does E25 mean on a Bosch dishwasher?
Drain pump fault — current draw out of spec or check valve stuck closed. Either the pump motor has failed or the rubber check valve at the top of the pump has hardened and won't open. $185–$385 depending on which.
How do I reset a Bosch dishwasher?
Hold the Start button for 3–5 seconds (varies by model) until the display clears. Or kill the breaker for 60 seconds. A reset clears a fault code but does not fix a mechanical drain problem — the code will return on the next cycle if there's still a blockage.
How much to fix a Bosch dishwasher not draining?
Filter / cover clean: $149 trip only. Check valve $185–$245. Drain pump $285–$385. Most Bosch drain repairs land $245–$385 all-in. The $149 trip fee is waived when you approve the repair.
