Bosch classixx slimline dishwasher not running through cycle

I have a bosch classixx dishwasher and it keeps trying to constantly drain even when is empty, it wont run through any cycle and even when reset still try's to drain, the only way to stop it is to unplug it, could anything be stuck in the system which is fairly easy to repair myself or do i call an engineer?

Fault is that there is a leak. the tray at base of dishwasher is full of water which operates a float and turns on drain pump. tilt over 45deg and water will run out and then it will work or remove bottom front panel and mop out (better). then find leak

How do I resolve f17 error message on bosch classixx 7

F17 is a time out fault on drain pump. Check all water hoses and drain pump for either blockage or restriction. Failing that, check your waste pipe is clear.

We have a bosch classixx free standing dishwasher and the base is filled with water, we ve removed the filter but there doesn t seem to be anything there causing the blockage.any ideas?

Hello Becky,

The most likely causes are a failed drain pump motor (or capacitor) or a jammed/broken pump impeller. There is a very simply simple test on classixx models which which help you to determine the cause, or where to look next.

1. Turn the wash cycle selector to any wash cycle so the "ON" light is illuminated, but do not press the START/STOP button.
2. Open the door and pull the lower basket out.
3. Locate the 'float', lift it up fully and keep it held up.

(The float is a dome/mushroom shaped protrusion in the base of the washer just to the left of the drain and partially hidden by the spray arm)

When you lift the float, the drain pump should run instantly and the water should drain from the washer. If you can hear a low hum from the pump motor in the base of the washer, but the water doesn't drain, then it's likely that the pump impeller is jammed or it may have broken away from the spindle. If this is the case, try repeatedly lifting and dropping the float fairly rapidly. Repeated stop/start signals to the pump motor can sometimes free a stuck impeller.

If you cannot hear any noise from the base of the washer when you lift the float, then the drain pump motor or the motor capacitor may have failed. A failed capacitor is often accompanied by a buzzing noise. Further testing will be required to determine the exact cause of the fault.

Please try the simple test above and then post back with the results for further assistance.

Hope this helps.

Dishwasher not draining after a power cut

I would run the heated dry cycle a few times to try and get rid of that residual water, then restart the cycle and see if it work now. If it still is a problem try cleaning out the drain line behind the dishwasher, this is a very common problem with draining. If not that then might need a valve or if you have a new garbage disposal you need to punch out a peice of the plastic or it wont drain. Hope this helped, good luck

Washer does not fill with water

The problem is most likely that your drain valve is defective. If this happens, the water will pump out instead of circulating. There may also be something stuck in the drain valve causing it to stay open.

Bosch 24 in. SGS43C12 Classixx Free-Standing

if no drain, then no cycle. problem is probably that draining is not taking place. check the following: if plumbed in under the sink, remove drain hose from spigot and check no blockage. start any program - all programs start with drain. listen carefully for a low humming noise. if you hear this, it means you have something stuck in the pump impellor - bit of bone, cocktail stick etc. get back to me if you like with what you find
