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.

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
possible that drain pump is jammed with something or if this not the case it could be the circulating motor head is cloged up. being a built in appliance would def recommend calling out an engineer. unless drain pump can be got at from inside the dishwasher.
sorry cant be of much more help, meile appliances rarely give problems so dont see alot of them
Hi there - possible the inlet valve is blocked or faulty - have a look at the valve if its blocked first if not then the inlet valve is faulty... the problem is the G638 has 2 inlets - one is the the waterproof syatem with a large grey contration fitted to the tap, the other is located beneath the machine , a bit hard to get at...
will require a disconnection of services empty water from machine - tilt on the back - 4 screws on the bottom tray - here you will find the valve - should be located on the frontish right side..
Do be careful if you pursue the latter as its a delicate with little space to work with and costly if you break something else in the process...
Have a think about this first...Yes? then do remeber to disconnect the power.....
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.
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.
Hi. The above machine stops mid cycle and drain/fill light is on, also
error code F3E, have cleaned both hot and cold water inlet filters, also
checked drain pump and drain line, all ok. Machine drains with no
issues and fills with hot water, runs for a while then shuts down.
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
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.
