Water will not shut off keeps filling and overflows

water level sensor --switch -inlet valve failure ----the machine wont advance till water is at level requested so since it doesn't stop filling it wont cycle to wash -----------https://www.manua.ls/sanyo/asw-40ap/manual

check that the fill valve was installed correctly
adjust the float level so that when full the cistern water level is around 1/2" below the over flow pipe end
what you have now is that the inlet water is not being shut off correctly and the water is still coming in and flowing out of the overflow

Check page 17 of manual.
FE: OVERFLOW ERROR; Water is overflowing (water level frequency is over 213).If FE is displayed the drain pump will operate to drain the water automatically

Rather hard to understand your problem from the wording in the question but what I understand to be the case is that your tub fills up with water and overflows after the cycle is finished. Perhaps overnight water slowly fills the tub. This is due to the water inlet valve not shutting off all the way. The Inlet valve assembly needs to be replaced.

If it fills with water and starts the cycle and the water keeps running in then your water inlet valve on the back where the water supply comes in is sticking. It needs replacing.

Hello,Sounds like a problem with either the inlet valve or the pressure switch, way to determine which on is while it is filling pull the plug..if water keeps filling it's the inlet valve..if it stops filling it's the pressure switch..If you have any other questions or concerns please feel free to comment again..good luck!!

Try filling it again and stay with it, when it starts to get near the top, unplug it, if water continues coming out you need a new valve, if it stops, then the level switch inside the control panel is bad

water level sensor is not working properly
with your solenoids to shut off water
