I have a Miele WT945S washer which does not fill water on prewash and main wash.

There is a problem with the programming of the control board if this is occurring.

All you can do is turn off the water to the machine at the end of the full cycle and then run the spin cycle again to dry out the clothes. Then no water can enter the wash drum.

Otherwise you would need to turn off the water each time before the spin cycle concluded and thus before the machine began adding water again.

hi, the problem you are having with the "soak/prewash" light flashing after the wash has started is a common fault on the meile washing machine. Its a water sensor problem. remove all srews and bolts from front of machine and open the front panel. you will see a red in colour pressure switch at one oclock, there will be a black tube attached to it, remove the tube and replace it with a new one, or reverse the tube in reverse and you will find that the water intake level will be less and the fault of the "soak/prewash" light will no longer flash, problem solved. 0868887054 DAVID ASHBOURNE. MEATH.

If your PreWash is flashing then you have a pressure problem. You can dry using a washer machine cleaner or doing a hot cycle with white vinegar. If that doesn't help the electronic would have to be changed.

Check the tray before you fill the powder. There should not be any water. Once you switch it will drain along the water when water is showered inside the tray.

If you mean the Miele Washer/Dryer WT945, I've published some 'Tips' on the dryer problems. Hope these help. Best to read in order.

Bought a new washing machine. The motor had one of the coils open circuit and the cost of a new motor was nearly that of a replacement WM.

put on prewash cycle. note which tray water enters and that is the prewash tray.
put on wash cycle which has no prewash. note which tray water enters and that is main wash tray. remaining tray is rinse

sounds like water valve problem

If you use a program without prewash, the machine will not flush the prewash chamber in the drawer.

Hello E10 = Problems during water filling phase ? washing (Machine tries to fill for 10 min without reaching the level) Checks to do: Is there one of the tree valves that is not working? NO, Verify that tap and hoses are letting the water coming in. (tap open, hoses connected and not kinked) Is the wiring OK? (Measure the 3,8 K Ω of the valve from the cable Main board side: - between J6-1 and J6-5 wash valve; - between J6-2 and J6-4 prewash valve; -between J6-3 and J6-7 hot or bleach valve. if NO Replace the cable. Change the main Board Regards David Marsh
