Model G643 V1 Plus. Drain/inlet light comes on and sometimes all lights for all programmes flash. Any solution please.

SOURCE: Inlet/Drain light keeps flashing

Kenyanjoe, I have had the same problem with a G638 . the inlet/drain light flashed 30 sec after start up, (the machine must empty on start up, this did not happen), This caused it to lock out on alarm I removed the drain hose from the S trap,removed the non return valve from the filter, check the drain pump impellar is free, then blow down the drain hose back into the dishwasher to make sure it was not blocked then found the drain pipe on the S trap under the sink was restricted causing the machine not to empty in time for the cycle to continue causing it to lockout on inlet/drain alarm. Have a go , good luck. GUNNO

SOURCE: powder not dissolving drain/inlet light sometimes flashes

I would guess the detergent door is open and the powder comes out so, If water is going in then the pump is not pumping.

Listen for the water to fill then after it stops open the door to make sure it's full of water. If no water or not enough then replace the water valve. If you have water then the pump is not pumping.

I had the same problem on a 5 year old model. It was the main pump leaking from a perished seal causing the water protection microswitch to trip. This gives the symptoms you describe exactly. Parts cost from Miele was about £60 for a new seal. Fairly easy to fit.

SOURCE: intake/drain light is flashing

When this happens with my dishwasher it usually means that the drain is clogged with food/debris.  To fix 1) remove bottom dish rack from machine 2) using a small cup, scoop out as much water as possible 3) remove inlet drain cover and unsnap the plastic insert and remove 4) rinse the plastic part and reinstall 5) start machine 6) if light still flashes, repeat steps 3 4 and 5 and restart

Hi,

Sounds like something is caught in th drain pump as the unit has to drain first before anything else happens. Remove the filter and the non return valve which is under the clip in the sump of the unit. In the manual it shows you this. Make sure the drain pump is free of any foreign particles like broken glass. Then start the unit again so it goes to drain without the non return valve in place. This will then throw out any foreign particles as well.

or it could be the drain pump is activated all the time which is the noise you hear as there is a flood in the base of the unit which activates the float switch and constantly activates the drain pump until the water has gone. Isolate the unit at the power switch and remove the bottom panel under the door panel. Dry up the water as best possible with a towel. You will see the float at the front. Run the unit again and check for any water leaks. You may just have over sudded the unit with too much detergent. Only use 2 teaspoons of powder. To start with while testing don't use any detergent. Good luck

Testimonial: "Thank you for your excellent advice, the machine was flooded in the base when the panel was removed. "
