E4 Error bush dishwasher

Hi Chaps, I have a Bush DWFSGX146SS from Argos, I first developed an E8 fault shortly after a glass broke in the dishwasher’ i decided to have a look and see if something was stuck in the drain pump’ i noticed a small piece of glass that had scored the impeller and surrounding and thought i had removed the glass, the fault kept occurring from time to time so decided to take another look’ after researching i decided to have a look at the diverter valve motor’ when i removed it a piece of glass fell out’ i was chuffed thinking I’ve fixed this, to my disappointment when switched back on the machine flagged up E4′ i thought it may be water resting on the flood switch after all i had it on its side. the was signs of water so decide to slightly put it on its side for a day to drain all water from where it should be.
Once i put back together the same E4 code appeared ‘ this time ive removed it to the garden in order to take a good luck whats going on.
Ive checked the flood micro switch which is working fine, it could well be the divertor valve since removing it has damaged the seal which is creating water and pushing the float switch to activate ‘ ive changed the seal on the divertor motor’ but not yet put all back together’ as oi want to give it a good going over first.

have you any ideas guys ???
