Re: smeg diswasher

Is there a buzzing noise from the bottom of the machine as soon as you turn the power on?
E8 states the diverter valve has a fault.
Turn the machine and water supply off.

You can feel which part was making the buzzing by carefully touching each part under the machine (caution: shock risk!) It's a flattened conical shape in the middle, with two hoses connected to it, one screw and 4 thin wires.

Undo the screw, pull the hoses off by pressing the clips together, and disconnect the multiplug for the wires. The motor simply clips off the grey gearbox, and the gearbox itself is clipped to the valve body and retained with two screws.

If the seals on the valve are stiff, work some silicone into both the main bearing seal and into the valve faces themselves and the diverter should be OK.

Re: smeg diswasher

Thanks to hijoloo for pointing me in the right direction. The offending part is the diverter valve, a paddle inside blocks one of two outlets in turn actuated by a micro switch, a motor and reduction gears. Check switch for continuity with multimeter (ohms) then check motor and gears turn freely by hand. My problem was a stiff paddle due to limescale. Soak in boiling water to free off then oil cog (externally) and rebuild.
turn the washer on its side and open up the bottom black plastic plate, than disconnect the two black hoses from the white pumphouse in the middle of the washer. disconnect the connector and open carefully the housing by removing two screws and the motor. check the switch and clean the white housing. Check also if there is nothing inside the rotorhouse. after this build every thing back and hope that its running. it worked for me. succes!

No power or lights in the front panel

Check the fuse / circuit breaker inside washing machine. There may be a extra control circuit fuse normally on the control PCB.

DWF614SS smeg dishwasher E8 error code

The E8 fault is generated when the internal switch on the alternating valve fails to register that the diverter valve has switched over. It may be that the disc inside your valve isn't moving completetly over or the switch isn't working. The feedback from this device is to the main pcb, therefore there are only three parts involved, the pcb, the diverter valve and the wiring. It is possible to test the valve using a multimeter to confirm it is indeed switching properly.
I don't have a part number unfortunately but if you go to you'll be able to get the part number and price of the part.

Good luck with your repair.

The buzz that you hear is the water line solenoid. It probably is not opening up to let the water through. You should replace this solenoid and it will fix your problem as long as you have water coming up to the diswasher's solenoid valve.

Smeg Dishwasher - model unknown

model numbers for dishwashers are generally where you can get to from the front, if they are noit on the front panel then look inside the door rim where the rubber seal is, either a small sticker on the door rim itself (inside) or where the door fits on the main cabinet, open the door fully to look for this sticker, sometimes placed under the front of the lid

We have a Smeg SA8605W which has had a similar problem 3 times in its short 3 month life. The problem with ours is that the control panel on the front pushes against a very brittle plastic frame to activate the micro switches. Because of the brittle nature the 'fingers' of plastic break off and either get stuck holding the machine in a set cycle or break off fully so nothing functions. Gaffa tape or Elastoplast is a simple solution.
