Hotpoint WMA50, started on regular wash cycle, emptied water, but instead of spinning, all LED lights begin to cycle. i.e. flash from top to bottom and back again!? Any ideas.

hi there, check out page 13 toward the bottom

good luck

Door switch fault.

Victor. The prewash flashing is indicating a water fill issue. Rinse uses cold water only. check for clogged inlet screen on the cold water valve, and check if there is a screen on the supply valve also. If the inlet screen is all clogged up at the valve on the washer, you can clean it with a little windex and an old soft tooth brush. gently brush away any sediment or debris. If no filters are clogged, you will need to replace the fill valve assembley.

Hi! If the pre-wash light flashes it means you are not getting enough water in the machine, check the pressure chamber, pressure switch, fill hoses and valves. For a workshop manual on the WMA50 which includes fault finding, visit www.selfix-uk.co.uk

You have most likely selected by mistake the no spin option coupled with extra rinse  - press again the rinse button to unselect that and put the spin speed at max.

Could be motor brushes....

you may be putting it in the wrong slot they are either marked as 1,2, or 3 (3 being the one for softener) or you may just need to consult your manual

Running with a restricted water supply probably took out the pump.
The stator requires a steady water supply for cooling and lubrication. Without this accelerated wear between the stator & magnetic poles occurs.
This additional clearance makes the magnetism insufficient to spun the impellor.

Had same problem today with our machine. Brushes looked OK (although one appeared a little shorter than the other).
After removing and re-fitting the brushes, motor worked fine - suggesting that it was the brushes afterall.

Now looking for replacement brushes
