Miele Novotronic W980 WPS Washing Machine
My Miele W980 WPS washing machine is about 20 years old & was working perfectly until last weekend . I had it on timer and when I came down there were three red bars on the display and the red check inlet light was flashing. We disconnected the WPS box from the tap and connected it all up again...plus we found & fixed a leak on the isolation valve leading to the tap & had to turn the main stopcock on & off a few times The next wash worked perfectly, but yesterday there was only a dribble of water coming into the dispenser, the WPS box was humming slightly and the red inlet light was flashing again. I'd be very grateful for any suggestions. Thanks

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
Miele Novotronic W980 WPS intermittently not filling, check inlet light flashing
- The problem
- A Miele Novotronic W980 WPS, around 20 years old, stopped filling properly. The display showed three red bars and the red check inlet light flashed. On a later wash only a dribble of water entered the dispenser and the WPS box was heard humming slightly. After reconnecting the WPS box and fixing a leak on the isolation valve, one wash completed normally, but the fault returned intermittently.
- Likely cause
- The strongest diagnosis in the discussion is a water supply or fill-side restriction/problem in the plumbing, fill hose/WPS hose, tap or inlet valve path. A blocked pump filter was ruled out as unrelated to a no-fill fault.
- What fixed it
- Recommended action was to check water flow from the plumbing by disconnecting the fill connection and confirming a proper flow into a bucket, and to inspect the fill hose, tap and water valve/fill path rather than the drain pump filter. The exact repair was not confirmed in the thread.
- Checks to try
- Reconnected the WPS box to the tap
- Found and fixed a leak on the isolation valve
- Cleaned the filter at the bottom front of the machine
- Removed and cleaned the filter leading to the WPS box
- Checked the tap
- Observed only a dribble of water entering the dispenser
- Noted slight humming from the WPS box
- Advised to test whether water flows properly from the fill supply into a bucket
- Parts or tools mentioned
- WPS box
- Isolation valve
- Fill hose/filter
- Pump filter

Hello there. It sounds like there is a problem with the plumbing. Have you taken off the fill holes to the washing machine and turned on the water to check that water is flowing through it properly into a bucket down the sink? Not filling with water and a humming noise usually means the washing machine is energising the fill valve but no water is available - Washing machine won’t fill with water

Thanks Andy, so far we’ve tried emptying out & cleaning the filter at the bottom front of the machine, removing the waterproof system box from the tap,removing & cleaning the filter leading to the box & checked the tap. The bottom end of the hose doesn’t seem to come off...and there’s no separate back panel.
The next wash started off fine, but then the inlet light started flashing again but I managed to finish it off by pouring water directly into the drawer!
The filter at the bottom is for the pump. If blocked it will stop the washing machine from emptying the water. If it's not filling that's the fill hose, tap and water valve to check at the other end.
