Washer Dryer Won't Fill With Water

Servis M9824S washer dryer will not fill with water at programme start

The problem

A second-hand Servis washer dryer M9824S would not take in water at the start of a programme. The drain pump ran briefly, then nothing happened, and after about 20 seconds the pump ran again. If water was added manually, the machine would continue through a programme and the dryer function worked.

Likely cause

The strongest diagnosis discussed was a blocked pressure system or pressure chamber making the machine think it was already full, although this was not confirmed. The original poster also suspected either the pressure system or the PCB. No error lights were reported.

What fixed it

No repair was completed. The pressure chamber could not be accessed easily on this model, and the machine was not pursued further. The original poster decided not to spend more on it, partly because the drum bearings were also thought to be deteriorating. Replacement was effectively chosen instead of repair.

Checks to try

• Pressure switch pipe blown through at both ends and switch heard clicking
• Wire connections checked throughout the machine
• Pump cleaned
• Pump ball and associated pipes cleaned due to heavy gunge
• PCB visually checked with no obvious burnt components or wiring
• Pipes checked and reported not blocked
• Inlet valve had already been replaced by the seller
• Checked for flashing lights/error indication and none were present
