JennAir Flush Mount Code E:23: drain pump resistance wrong

What E:23 means

On the JennAir Flush Mount dishwasher for European cabinets, model JDB9600AW, E:23 is a drain pump error shown at the end of the program. It means the resistance values of the drain pump are wrong, so the control cannot treat the pump as healthy. You will see E:23 after the cycle ends, and standing water may remain in the tub.

Common causes of E:23

Drain pump winding is out of range
Wire or plug at the drain pump is damaged
Control cannot read the pump correctly

✓ One safe check you can try

1. Turn the dishwasher off at the breaker for a minute and restart it. 2. Run a short cycle and see if the tub drains. 3. If water is left, scoop it out with a cup and towel, and check the filter and the drain hose for kinks. 4. Do not open any panel. 5. If E:23 returns, call us.

! Why to stop there

Pump resistance can only be read with a meter at the pump connection.
A kinked hose is a free fix, but a bad pump winding is not.
Water left in the tub can spill when you pull the unit from its cabinet.
We tell you the price in writing first and give a 30-day workmanship warranty.

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:23E:23 questions

Does E:23 mean the pump is clogged?

Not exactly. E:23 is about wrong resistance values, which is an electrical reading. A clog gives a different code, E:25. Still, check the filter and hose, since a jam can overload a pump.

Can I run the dishwasher while E:23 shows?

It may wash but fail to drain at the end. Standing water can smell and leave residue. Run it only if you can check the tub after each cycle.

Is E:23 specific to the flush mount model?

This explanation applies to the JDB9600AW flush mount dishwasher for European-style cabinets. Other JennAir dishwashers use different codes, so give us your full model number.
