Re: Zanussi ZT 695 flashing lights
This is classed as an L1 error.
Eight different probs, but suspect anti flooding device as first port of call.
First unplug machine to make safe.
As in most situations dishwasher will be slotted in below worktop, pull out and put a towel at the rear of appliance then tip back 45{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d}, water may come out (reason for towel) if so this confirms overflow to sump tray.
Stop using tablets and go back to powder.
If this does not cure problem click on Find an engineer as you have done as much as you can without further expert advice.
