JennAir Flush-Mount Code E:01: Power module problem ends the program

What E:01 means

On the JennAir flush-mount dishwasher built for European-size cabinets, such as the JDB9600AW, E:01 reports an internal problem on the power module. The part that controls the pump, or the part that switches the pump between its two jobs, is not responding as it should. The program ends early, the display shows E:01, and the dishes may still be dirty with some water left in the tub.

Common causes of E:01

Pump control circuit on the power module not responding
Pump switchover on the power module stuck or failed
Power module needing replacement after the two checks above

✓ One safe check you can try

1. Open the door, then close it firmly and let the machine sit for a minute. 2. Cut power at the breaker for a minute, then restore it. 3. Run a short rinse program with an empty tub. 4. If water is still standing in the bottom, check that the filter is clean and the drain hose has no kink. If E:01 returns, stop and call us.

! Why to stop there

E:01 points to the electronics that drive the pump, and guessing at that board gets expensive quickly.
Power modules sit in a wet appliance, so testing them is not something to try live.
Repeated restarts can leave water standing in the tub, which is a leak risk for the cabinet floor.
A confirmed diagnosis first means you get a written price before any part is ordered.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

E:01E:01 questions

Does E:01 mean the pump itself is broken?

Not necessarily. The wording points to the power module's pump control or its pump switchover, not the pump motor. The pump may be perfectly fine while the board that commands it has failed.

Why did the program just stop?

The machine ends the program when it cannot trust its own pump control. That is a protective step, so the tub may still hold water and the dishes will need a new wash after the repair.

Will a power reset clear it?

A reset can clear a one-time glitch, so it is worth one try. If E:01 comes back during the next program, the module needs a technician, and we quote the price in writing before any work starts.
