Hi,
My ISE10 has developed a fault today. No matter what programme I use it will not pump out. Code F3 comes up on the screen. The sump drain is clear, no coins or clips. Its not been an intermittent fault, it was working fine last night then just stopped draining today. No strange noises. No leaks. No previous problems. Any suggestions for candidate faults ?
Re: ISE 10 1406W will not drain
Drain it fully then set it to a spin programme with the pump filter removed and observe the pump action.
If the pump runs smoothly then it’s possible you have an obstruction on the outlet side.
I have seen a five pence piece get past the filter and into the pump outlet hose. Does the outlet hose slot into a standpipe or is it connected to the under sink waste pipe?
If the latter then an obstruction where the hose is connected to the sink plumbing is also a possibility.

Can I just check that by the ‘pump filter’ you mean the ‘drain plug screw in’ at the front of the machine ?
Re: ISE 10 1406W will not drain
Yes – the pump runs freely and without obstruction. The pump outlet hose is connected to an undersink wastepipe – that connection is the next thing to check.
Re: ISE 10 1406W will not drain
If it is all clear there then try and blow down the pipe back to the pump, there should be little or no resistance.
Re: ISE 10 1406W will not drain
Problem solved – thank you very much. A 5p piece and a piece of plastic had got past the filter and were acting as seal at the end of the outlet hose at the connection with the under sink waste pipe. Great advice from here as always !!
