Simpson Esprit 700 washing machine

Hi all
This machine does not detect water level and consequently overflows when filling. Can anyone help with service manual or advice?
Thanks

Does it have an air operated water level sensor?

These are usually a small round unit with wires attached, and there's a small hose (around 8 mm OD) which goes from it to the bowl.

If it's got one, there's a possibility it's faulty or there's an air-lock in the hose.
Air locks can happen if the machine is tilted over or laid on its back (especially when transporting).

Pull the hose off the bowl end and blow gently into it. You should hear the sensor click, blow a little harder and it should click a second time.
Fit the hose back to the bowl.

Check operation of the machine. If it still overflows, the sensor is most likely faulty.

Hi Studio1
I have followed your advice but the pressure switch clicks only once no matter how hard you blow. I have got the machine working by setting water level to low so it fills about half way.
I am searching on-line for a replacement pressure switch.
Cheers

I probably should have mentioned that not all pressure sensors are 'two-stage' (two clicks).
The older F & P ones generally were, but the smaller sensors are only a one-stage unit.
It's more than likely to be your problem.

make sure the air line to the switch isn't damage, even slightly can leak

Pressure switch replaced and it's all good.
Got it from onlineappliancespares.com.au
Can't complain about the service.
I ordered it just after 9AM on Wednesday and it was on my doorstep Thursday morning.

It appears that my success was short lived.
After a couple of washes, the problem has reoccured.
However, a new piece of information may shed light on the cause.
The machine started the wash cycle after filling but the water kept coming in.
Also, lifting the lid did not cut off the flow as it usually does.
I now suspect that the water valve solenoid may be sticking open from time to time. Another clue is that when the lid is lifted, the water flow sometime takes a few seconds to stop. I will be going back to my mates place soon to try and prove the theory. As they only use cold water for the wash, I will swap the water and electrical connctions over to the hot water valve.
