Question about Miele 24 in. G646SC Plus Free-Standing Dishwasher

1 Answer

Drain pump runs continuously

This started with wash programmes at end of wash cycle but a pre-wash would work fine. Pump would run for extended period then inlet/outlet light would come on.
I cleaned all filters, checked supply/drain hoses, checked the leak switch at in bottom tray and another pressure operated switch located back rh corner connected to filter sump(?) by black hose. All seemed servicable. But no real improvement in fault.
Any other switches etc I can check before reorting to the (very expensive) circuit board. Does anyone have a service manual and/or illustrated parts catalogue? or know where/how to obtain one?
Thanks in advance

    I have the same problem on a Miele G647 SC Plus. Did you manage to solve this and if so what was the problem causing it to stall before the drying cycle? Thanks in advance.

Zanussi zdt 6053 usually will not run full cycle (on any cycle) but stops with constant error beeps. But it is draining ok and sometimes goes full cycle (not often) Any ideas?


Could be anything!
If you suspect that there is a fault then it will be displayed by blinking LED "END OF CYCLE". As the display of failure in hexadecimal code it can flash up to max. 15 times than short pause and after that repeat fault code. You must to count the number of times the LED "END OF CYCLE" flash up.

Example from user manual: Anti-flood device is activated.
- continuous flashing of the indicator light of the running programme
- 3 intermittent audible signals
- 3 flashes of the END OF CYCLE indicator light
(which means "i30" fault code, the cycle is interrupted and the
drain pump switches on).
Possible causes:
Water leakage from the tub - sump and various connections
(pump, upper spray arm duct etc.); floating sensor blocked
mechanically; microswitch faulty; fill solenoid blocked
mechanically; circuit board faulty (solenoid triac short-circuited);
wiring faulty.
26226179-aipk5px1bmfkdpsmrgevaqwn-3-1.jpg Could be also:
To cancel a washing programme in progress:
- Open the dishwasher's door.
- Press the programme selection/cancel button for about 3 seconds,
until the indicator light of the running programme turns off and the
END OF CYCLE indicator light flashes, indicating that the running
programme has been cancelled and that the machine has
returned to setting mode. It is now possible to select another
washing programme. If a new washing programme will be
selected, check that there is detergent in the detergent dispenser.

NOTE: only during the drying phase, if the dishwasher's door will be opened and remains open for more then 30 seconds, the running programme will be automatically cancelled and the machine will return to setting mode. This will happen, always only during the drying phase, also when the machine is switched off by pressing the
On/Off button and remains switched off for more then 30 seconds.

My Hotpoint BWM129 drains at end of a cycle but doesn't proceed to spin, fault lights flashing are rapid Door locked and intermittent Delay Start. Does this fault code indicate a faulty drain pump or


Engine fault or main board fault. Most likely main board.
Check cable harness from main board to engine. Check the carbon brushes on the engine. If its all okay, replace main board

Good Day,
Your washing machine is fully automatic?
the washing cycle is normal?
if yes do the same maybe it will help you.
for the fully automatic washing machine mostly have drain pump, please check the filter of your drain pump, how? remove the cup of your drain pump like a ordinary cup, screw it clock wise or counter clock wise.
Remove drain pump filter and clean it, some hair pins, cotton buds or coins or any small item that coz of clog up.
if your washing machine dont have drain pump ,but fully automatic check the drain motor if running or not? how? open the back cover for top loader washing machine only, select spin cycle and press start to see the drain motor running? the drain motor is like a small box with small wire to pull the lever of the drain to remove water inside, if the motor running or pull the lever of the water pipe but water still inside the washing machine, remove the drain cup or cover and clean it or check if have coin or cloth inside that coz of clog or water stuck,
if the drain pump or drain motor is weak this is will cause and long time draining or totally not running the drain pump or drain motor and its cause of totally stop the cycle of washing machine in rinse time or spin time, because all fully automatic washing machine, after washing cycle the drain pump or drain motor must be on, to remove water before start the next cycle. rinse or spin cycle.

The washer floods at the end of the cycle the pump is working this i know because when i manualy lift the mushroom float it pumps out could it be that there is a membrane in the mushroom float that is...


Hi there,

I'm not entirely sure what you mean by "floods at the end of the cycle". Is water leaking from the washer and where from?

The mushroom float isn't a water level sensor to determine when the washer should pump out. It's a second level safety feature to prevent flooding if the washer overfills. The flow meter regulates the water level in the washer.

Your pump is obviously working and there is no blockage in the drain hose, etc as the water pumps out when you lift the mushroom float. It sounds like the pump isn't receiving a signal from the controller to pump out at the end of the wash cycle. Lifting the float bypasses the controller and runs the drain pump.

Please try the following simple test:

1. Switch the programme selector to "Off"
2. Empty a bucket of water into the bottom of the washer
3. Turn the programme selector to any wash cycle
4. Press and hold the Reset button (start/stop) for at least 3 seconds. The washer should drain.

Please try this test and let me know if the washer pumps out. Please can you also be a little more specific about how and where the washer is flooding.

Thanks,
BElectric

Whirlpool Roper Gets to Rinse then water runs but will not fill


The contacts for the outlet pump have fused together in the programmer so that as soon as you apply power the pump motor starts running.

Remove the power first

Quick check is to take off the back panel locate the pump and remove one of the supply leads
put some insulating tape around the end of the lead you have taken off in case it shorts out then put the power back on and try the machine, it should then fill and start to agitate .

If that works then you need a new programmer .

Turn off the power , replace the lead and then put the machine back on to drain out the water

There is a recall on the control board of many of these models, butyour problem is likely not related. It sounds like a plugged drain system or a possible bad drain pump. That's why you are hearing the pump running constantly. I have written a guide to help. It is here. Thanks!

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.
