ISE 1606W Drain Problem

[Pukka]

Hi All,

We have an ISE machine, that has been running great for year. Last night the machine just woke up and started the drain pump but the door was open :eeek:

so today i have a had a look and the machine fills ok, when set to the drain cycle it start the pump and it runs for just over a minute stops and then starts pumping again. shows an F3 error after a while.

if i remove the presure switch hose and switch the machine on it just keeps filling, when connected i can hear the presure switch clicking on fill and empty.

Presure hose is clear and no limescale in the chamber.
Nothing in the pump or hose.

Out of ideas now can anyone help 🙂 , could it be the presure switch? what does the presure sensor do?

I have tested the pressure sensor, when the pump is running it show .6v and 1.3v when full

Has anyone got an idea?

Ok here is an update, I replaced the pressure sensor and this did not fix the machine. So i am going to guess its the mainboard I think its a power supply problem not providing 5v.

All of the parts are now on ebay so hopefully someone else can keep there machine running.
