Inlet drain lights flashing

I think you may find a button or other debris in the pump housing preventing the pump from emptying all the used water eric

White knight dishwasher flashing red light and. Won't. Empty .
could be something in drain pump need to bail the water out of dishwasher best way is a small scoop take filter out and you can get to the lowest point of sump. Take water out and use sponge for the dregs . Un plug appliance and turn water off remove inlet hose and waste pipe. Lay the appliance on its back and remove the base of the appliance you will then see the drain pump remove 3 screw and gently remove pump head and remove object but watch finger if it's a shard of glass .

Run the dishwasher through a test mode


Test Mode


Make sure the appliance is empty of water before running Diagnostics as it does not pump out before starting to fill and therefore you could overfill the appliance.
Open the door and set the program to the first program. (Normally rinse).
Turn the power off.
Press and hold the start button and while holding turn the power on.
After a little while the start button will flash, release the button.
Press the start button once and close the dishwasher door.
The machine will now run through a diagnostic routine.
Should take about 20 mins.
The machine will stop during diagnostics if an error is found and will display the error code. If no error is found it will complete the diagnostics and end the programme.

To exit diagnostics at any time just press and hold the start button till the programme is cancelled

either the inlet water valve is bad and needs to be replaced or the controller for it is not cutting off the electricty to it, If you are going to replace something, replace the water inlet solenoid valve.

I found all of these tips helpful although my issue was slightly different. The styrofoam float had become slightly warped with age and was triggering the switch while dry. Shaving a little of the foam off has returned my dishwasher to working order.

inlet/drain flashing wont drain water

Usually indicates a intake or drain fault - could be a plugged drain line at the garbage disposal or insufficient water coming into the unit

Could it be.Try to open and look the fuse inside.Opps try to see the warranty of applian.

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
