Jenn-Air Dishwasher Error Code E:22

E:22 indicates a circulation pump fault related to the heat pump being blocked or unable to operate correctly. The dishwasher detects that the pump cannot spin or circulate water properly and ends the programme to protect the motor from damage. The fault is most often caused by a foreign object lodged in the pump impeller, but can also result from a failed pump motor or electrical connection issue.

No, you should not attempt to run the dishwasher while the E:22 code is active. The appliance has already ended the programme automatically as a protective measure, and forcing repeated cycles with a blocked or failing pump can cause the motor to overheat or burn out. Address the underlying cause before using the dishwasher again.

If the fault is caused only by a foreign object blockage that you can clear yourself, there may be no parts cost involved. If the heat pump assembly needs replacement, parts alone typically range from $150 to $350 depending on the specific model, with labor adding $100 to $200 or more if a technician performs the repair. Wiring or connector repairs generally fall at the lower end of the cost range.

Start by removing the lower spray arm and filter assembly to access the heat pump area, then inspect the pump impeller for any foreign objects such as glass fragments, bone chips, or debris. Clear any obstruction you find and reassemble the components before running a test cycle. If the error returns after clearing the blockage, the heat pump unit may need to be replaced by a qualified technician.

A reset may temporarily clear the error code from the display, but the fault will return as soon as the dishwasher attempts to run if the underlying problem has not been resolved. The blocked or failed heat pump must be inspected and corrected first. Resetting without fixing the root cause risks additional damage to the pump motor.
