Question about Washing Machines

1 Answer

Water fill level is incorrect, probably faulty pressure switch.

If I do not use my washing machine for a few weeks it overfills the drum and water spills out during washing, I suspect the water level pressure switch gets stuck. It usually settles down after 2 uses. Now it is underfilling during wash and rinse cycles so that washing is not cleaned or rinsed. I think the water level pressure switch is at fault because if I disconnect the vacume tube during the cycle, then reconnect it then overfills with water (double dose). There are 4 plastic adjustment screws on the pressure switch. Please can you explain what each of these screws do and if there is any way I can service the pressure switch?

    When filling with water, my Lavamat 88730 stops filling when the drum has about 3cm of water. The door button light stays red and everything stops working. You cannot open the door. The door light just flashes red if you press Pause. You can only open the door with a coin using the emergency door opener. If you then empty the water manually, the door light turns back to green and everything works normally again. I've checked the main board and there's no sign of failure (like burn marks). The spin and drain cycles work fine (if you start with an empty drum) But none of the washing cycles work.(well they do for the first minute or so).

    I imagine that it may have something to do with the wter level sensor. But where is it? and how do I check it?

The washing machine is overfilling the water?

A defect in the water-inlet valve .The water inlet valve is the device which allows the water in the machine when the machine is turned on.but if the valve is faulty then it will not stop water to the machine even when its turned the washing machine overfills with water.
The valve is located at the back of the washer, and it will have water hoses hooked up to the back of it. Shut off the supply of water to your washer. Disconnect both hoses at the back of the washer. Before removing or checking the need to replace the valve if its faulty. If the water -inlet valve is checked OK.Then the other possibility to check out is the Water-level switch.The Water-level switch is the part that senses the water in the tub.if the water reaches to its required command the water supply to stop.But if the switch is faulty then it will not sense the water and water keeps on filling and at last water overfills due to Water-level switch not working properly. The Water-level switch is located at the bottom of the outer tub in the washing machine. This will help.Thanks.

What eroor8 in weat point washing machine

Error 8 Washing machine has detected an
overfill situation This error code can be caused by
overfoaming which is a result of overloading (see this article) or by overdosing or, incorrect detergent as
the pressure sensor will falsely read
that there is too much water in the
washing machine. Also check the pressure sensor and
that the machine has not actually
overfilled with water. Check for overfoaming or over
soaping Check the air chamber and the
pressure switch hose Check water level sensor Check wiring to water pressure
sensor Check connections to water level
sensor Check main electronic controller

My zannusi washing machine is pouring out water when on the rinse. water is coming out from front and both sides?


The problem is probably caused by overfilling, in which case the faulty part is usually pressure switch. Check the gasket between the door and drum for leaks. Check if the inlet valve is stuck open and check that the control module is working then eventually test and replace the pressure switch, which is the part that detects water level and stops filling.

Washing machine overfills and wont cycle to agitate

It is possible that the water level sensor is not working to switch off the inlet valve. So drain out and check the water level sensor, it is a pressure switch and can be checked if the diaphragm is damaged.
This sensore is fitted on the drum and works as the water fills, the water enters the jacket and pushes the switch on.
Hope this tip helps you.

Hi my ariston a1636 doesnt seem to pump water out it is now full to the brim and wont open the last two or three washes water came seeping out the draw is there a blockage in my pump

Could be but think more of an overfill fault cased by a blockage @ the pressure switch this controls the level of water in the drum shutting off fill valves. The pressure switch or air switch operates at 3 psi it is round with wiring onto it and has a tube connected to it ....make sure the Tube and chamber tat feeds this is clear as this is common to fail the valve and result in overfill,Apart from a faulty fill valve of course, this should cut off when power is removed.....good luck

Ariston Margherita ald 1 40 Error code H2O

H2O is the symbol for WATER and probably indicates a WATER related fault on your machine. A pressure switch is the normal way the machines 'sense' when the level is sufficient. Overfilling suggests a faulty switch, which will need to be replaced by a technician. Also, ensure that the machine drains as it should, if not, the pump filter may be blocked.

Hotpoint Washing Machine Model # VBXR1060T4WB Filling Problem

problem could be the pressure stat which is a switch which detects water level or the pipe leading up to this switch or the air chamber the pipe goes to.
take top off. locate the pressure switch - has a small diameter pipe going to it. remove pipe and fit a similiar one. put on fill and pressurise this pipe by mouth and water fill should stop. if it doesn't, then switch is faulty.
if this is ok, examine carefully the small diameter pipe for splits and blockage. also check the air chamber for build up of gunge
