Jenn-Air Dishwasher Error Code E:24

E:24 indicates a drain pump fault where the resistance values of the drain pump motor windings have been measured as incorrect by the control board. The dishwasher ends the running programme automatically when this code is detected. The fault can originate from the pump motor itself, the wiring harness, or the non-return valve in the drain line.

No, it is not advisable to continue using the dishwasher while E:24 is active. The appliance ends the programme automatically for a reason: running a faulty drain pump can lead to water not being expelled properly, potential motor burnout, or water damage inside the unit. The fault should be diagnosed and resolved before running another cycle.

Repair costs vary depending on the root cause. If the fix is limited to cleaning a blocked impeller or reseating a connector, costs may be minimal aside from a service call fee, typically in the range of $75 to $150. Replacing the drain pump motor can cost between $150 and $350 including parts and labor. A control board replacement, if required, generally falls in the $200 to $450 range depending on parts availability and local labor rates.

Start by inspecting all wiring and connectors between the control board and the drain pump for corrosion, damage, or loose plugs. Next, use a multimeter to measure the resistance across the drain pump motor windings and compare the reading to the expected value. Also check the non-return valve for leaks or blockages. If the pump windings test out of range, the pump motor will need to be replaced.

A reset may temporarily clear the code from the display, but the error will return if the underlying fault is not corrected. Because E:24 is triggered by an out-of-range resistance condition in the drain pump circuit, the physical cause must be identified and repaired. Resetting without fixing the root issue will result in the same fault code appearing again, typically during the next drain cycle.
