Bosch Washer Error Code E:22

E:22 means the washer has detected water at or above the overflow level inside the machine. The control board stops the cycle as a safety measure to prevent flooding. The fault is linked to the drain pump, drain hose, or inlet valve, one or more of which is not functioning correctly. Diagnosis starts with running test mode P9 to evaluate drain pump operation.

No, you should not run the washer while E:22 is active. The error indicates an overflow condition, meaning the machine cannot properly control water levels. Continuing to run it risks water damage to the washer's electrical components, the floor, and surrounding cabinetry. Address the drain pump, hose, and inlet valve before resuming use.

Repair costs vary depending on the cause. Cleaning the drain hose or pump filter costs nothing beyond time, or a service call fee of roughly $75 to $150 if a technician performs it. A replacement drain pump typically ranges from $40 to $120 for the part, with labor adding $100 to $200 at a repair shop. An inlet valve replacement is generally similar in part cost, ranging from $30 to $90, with comparable labor rates.

Some causes of E:22 are DIY-friendly, particularly cleaning a clogged drain hose or the pump filter, which requires no special tools. If the issue is a failed drain pump or a stuck inlet valve, replacing those components is a moderate-difficulty repair that requires disconnecting water supply lines and electrical connectors. Running test P9 first will help narrow down whether the pump is the source before purchasing parts.

A power reset may temporarily clear the error display, but if the underlying fault is not corrected, E:22 will return as soon as the machine attempts to fill or drain again. Resetting is useful for confirming whether the fault is intermittent, but it does not fix a blocked pump, clogged hose, or faulty inlet valve. The root cause must be resolved for the error to stay cleared.
