I have aquarius+ wf740..... when I switch machine on the wash enhance is flashing and power on/off is solid. Once I click any button the wash enhance stops flashing However the buttons do nothing on off won't turn machine off the main dial program select works only. If I leave the machine it keeps running test....the drum spins, door locks etc. Now I have checked outlet and also blown into pump switch after filling drum with water....it empties. Checked all connections on PCB and front display they're good... also checked front panel buttons are being push properly and done continuity test on the actual switches...all OK. I cannot locate heater element though. Any suggestions as to problem as the test seems to run fine though it doesn't fill with water I Dont know if that would be part of the test cycle. Obviously front panel buttons work as when pressed the flashing wash enhance stops.
