JennAir Flush Mount Code E:26: water switch problem

What E:26 means

On the JennAir Flush Mount dishwasher for European cabinets, model JDB9600AW, E:26 refers to the water switch. The switch is either permanently activated, or no impulses come from it even when it should be working. The control cannot count water properly, so it shows E:26. Owners may notice incomplete filling, wrong water levels or the cycle stopping early. Dishes may come out poorly rinsed because the water amount is not tracked correctly.

Common causes of E:26

Water switch is stuck on
Water switch gives no signal
Wiring or connector at the switch is loose
Water inlet supply is too weak to move the switch

✓ One safe check you can try

1. Check the water supply valve under the sink is fully open. 2. Make sure the fill hose is not kinked. 3. Turn the dishwasher off at the breaker for a minute, then restart a short cycle. 4. Watch whether the tub fills. 5. If E:26 reappears, stop and call us.

E:26E:26 questions

What is a water switch in a dishwasher?

It is a sensing device that counts or detects water coming into the tub. The control uses it to decide how much water the cycle gets. If it sends nothing or a constant signal, E:26 appears.

Can low water pressure cause E:26?

It can reduce the impulses the switch sends. Open the supply valve fully and check the hose. If pressure is normal and E:26 returns, the switch is the likelier cause.

Should I worry about leaks with E:26?

If the switch sticks on, the control may not stop filling properly. Watch the first minutes of a cycle, and if water rises too high, shut off the valve and call us.
