JennAir Flush-Mount Code E:05: Water switch triac failed

What E:05 means

E:05 on a JennAir flush-mount dishwasher for European-size cabinets, such as the JDB9600AW, signals an internal power module problem with the water switch. The triac that drives the water switch motor is defective, so the water switch runs continuously. The program ends with a drain. The listed repair is a replacement power module. Expect a stopped wash, water pumped out and the code on screen, with the load unfinished and still dirty.

Common causes of E:05

Triac for the water switch motor defective
Power module needing replacement

✓ One safe check you can try

1. Drop the circuit breaker for a minute and then restore the power. 2. Open the door and check that the tub is empty or draining. 3. Run a short program to see if E:05 repeats. 4. If it does, leave it and call us. Do not try to reach the control area or the switch motor.

! Why to stop there

The triac is an electronic part soldered onto the module and is not an owner repair.
The running water switch can leave wash water moving the wrong way and fill the base.
Testing live electronics near water is dangerous.
We confirm and quote the module replacement before ordering.

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:05E:05 questions

What is the water switch?

It directs water between wash zones inside the machine. A motor moves it, and a triac on the power module tells the motor when to run. In E:05 that triac is stuck on.

Why does the program end with draining?

The machine detects the switch running without control and ends the program. It drains the water as a safe step, so dishes are left unfinished.

Can I reset it myself?

A power reset is safe to try once. Because the cause is a defective triac, a lasting fix needs a new power module, which we replace after quoting the price in writing.
