Miele G638 dishwasher.

The Inlet/Drain light has started comming on and it stops the dishwasher mid cycle,I cannot find the manual for the machine but I suspect that the pump might be the cause because there is water in the machine when I open it,the drain seems clear and the fault only happens every third or fourth cycle.Even a description of what the inlet/drain light means would be a start.Any help is appricated,Thanks John

Re: Miele G638 dishwasher.

Hi John I have the same problem, the manual says that it is because the water level is to low, this is checked by opening the door after the machine has stopped filling and before it starts to wash, the level should be 4mm above the main plastic filter ring, the level has two settings, these can be adjusted by pressing the start button and the On/Off button at the same time, release the start button and turn the control to economy 45,if the start light does not come on the level is set to normal, to increase level press the start button again and the light should come on, this will give you an increased filling time. it did no help me but it may help you. good luck

Hi, We have a G638 plus and have it connected to the cold water tap. When we press start, it fills the machine with water and once the machine has been filled, the program doesn't start and after 2-3...


Intake/Drain light flashing means an issue while draining. You would need to check for air gap on the dishwasher, it may be clogged. It prevents dishwasher from draining, sometimes the drain flow is restricted due to gunk. Cleaning or bypassing the air gap will resolve the issue. If this doesn't resolve the issue then it is due to seized (or stuck) drain pump. Disconnect the power to the dishwasher or turn off the breaker to the dishwasher. Tip machine on its back; remove screws that hold the bottom tray on. Remove the hoses to the main motor, remove electrical connections & remove motor (single screw holds motor, it is on the outside back of the machine). Try to rotate the motor (use WD40 is necessary). If you cannot rotate it, then motor will be required. If the error still appears then cancel the error message, turn the rotary selector switch to "Stop/End" or press the "Start/Stop" switch for approx. 5 secs. Switch the appliance off and then back on again. Hope this helps... Please post back if you need more information.

Does anyone know why a Miele diswasher will start to wash fine and then stop with the inlet/drain light flashing after a few mins? I looked at the pressure stat at the bottom of motor and when i blow in it...

you may have something rapped around the impellers of the circulation pump causing low water pressure. the unit will start and stop to try to clear the blockage. if the circulation pump is really jammed the inlet/drain light will light. it could be a faulty pressure switch but they are not common to fail.

Hope this helps

The G638 finished its cycle but didn't completely

pump maybe on it's way out, though i doubt it, is the washing machine on the same drain out? if so you may have back wash, another could be lengh of drain hose, i had the same problem with my miele dishwasher because of the position in the kitchen i doubled up the drain hose and though it pumped out fine, with the volume of water left in the hose it came back in untill i repositioned the drain hose so it could't run back, hope this helps.

Meile G638 I Plus dishwasher

Problem solved, the dishwasher starts its wash cycle with a drain sequence, the pan did not drain in time for the wash cycle to continue , thererfor locking it out on inlet/drain alarm. I removed the drain hose from the S trap, then the non-return valve from the filter basket, made sure the drain pump impelar was free, blew down the drain hose back into dishwasher to clear any waste in the pipe,then found a block in the S trap orifis, after clearing that, reasembled and test run on cold pre wash cycle this runs for aprox 10 min.customer was very happy.

Dishwasher does not complete cycle

It could be a clogged in the drain line. Often the problem is at the point where the drain line attaches to the garbage disposer or household drain line. You should remove this line and clear it form any debris in the hose or the hose connection. Be sure to reattach the hose before starting the dishwasher again. Good luck!

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

Dishwasher not working

Hi Frazzledmum, Miele have a safety float switch in the bottom of the machine. (The float is a polystyrene disc). If the machine leaks for any reason, then the water sits in the bottom tray raises the float switch & all your dishwasher will do is activate the drain pump and flash those red lights at you. The reason is that somewhere under the machine there is a leak that needs to be investigated & repaired so in this instance I'm affraid that you will have to call a serviceman. Kind regards
