Sounds like there is a problem with the drain. But I suspect there is also some water in the tray under the dishwasher. There is a float switch in the tray which will run the drain pump. I usually use a shopvac to clear the water from the tray. Check the pump impeller by putting you finger into the pump from inside the dishwasher. It is on the right side under the screens. If the impeller is loose then it could be a bad pump. If you have recently replaced your disposal, make sure the plug is removed where the dishwasher drains into it. You would be surprised how often this is forgotten! Hope this helps, feel free to ask if there is anything else!

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.

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.

Dishes not cleaning after full cycle running


Your screens are plugged with food residue in the bottom of the unit. clean it out. You can use 1 gallon of white vinegar for your wash after you clean the screens. Start your washer to fill with water but after the water starts, open your door and pore all of the gallon in the unit. Let it now run for 4 minutes and stop it by opening the door. Leave the door slightly open for 1 hour. close the door and let the cycle continue for 4 more minutes. open the door and repeat it a couple of more times. Let it sit all night with the vinegar in it and in the morning - close the door and let the cycle continue to the end. This should help soften and clean out the food particles in the unit. You can repeat the process and get a better cleaning then too. All the scale should be off your dishes now.

For Miele Dishwasher G2470SCVI Need help with remaining water in the bottom. Model# G2470 SCV1 SF Type-HG03. Runs through the entire cycle,long,short ect..everything is clean and dishes look great but


see this causes and fix it. God bless you
Belt, Water Pump Although few dishwashers have a water pump belt, if the dishwasher won't drain there might be a worn or broken water pump belt. After removing the lower kick panel the motor can be seen in the front, the water pump belt is on the bottom of the motor.

Drain Pump If the dishwasher won't drain, the drain pump might be defective. Test the pump motor with an Ohm meter. Drain pumps are not repairable, if it's defective it will need to be replaced.

Drain Impeller The drain impeller is attached to the pump and pushes the water out of the dishwasher, through the drain tube and into the garbage disposer or drain line. If the dishwasher won't drain, the drain impeller might be broken or worn out. Replace both the impeller and seal at the same time.

Drain Solenoid Kit If the dishwasher won't drain, the drain solenoid kit might need to be replaced. The drain solenoid is an actuator that opens a flap to allow the water to drain.
Drain Valve The drain valve can get clogged with debris and should be cleaned out if the dishwasher won't drain. If it seems clear of debris but won't actuate, it will need to be replaced. The drain valve is not repairable.
Pump and Motor Assembly If the dishwasher won't drain, the pump and motor assembly might be defective. If the motor runs during the drain cycle, check for a blockage in the drain line. If the motor won't run during the drain cycle or if it just hums when it should be running, the pump and motor assembly might need to be replaced.

Clogged or Improperly Installed Garbage Disposer If the dishwasher won't drain and the garbage disposer was installed recently, the installer might have forgotten to knock out the drain plug from this disposer. All garbage disposers are sold with a solid plug in the drain tube for situations where a dishwasher isn't connected. However, if the dishwasher is connected, the plug will need to be removed. If the disposer wasn't replaced recently, remove the dishwasher drain hose from the disposer and clean out both the fitting on the disposer and the end of the drain hose. These are the most common places to find an obstruction if the dishwasher won't drain.

Drain Hose If the dishwasher won't drain the drain hose might be clogged. Remove the drain hose from both the dishwasher and the sink drain to clean it out. The most common place for an obstruction is at the garbage disposer.

Check Valve If the dishwasher won't drain the check valve might be stuck closed. The check valve is a small plastic device which prevents water from returning to the dishwasher after it has drained. If the valve gets stuck closed, it will prevent the water from draining. The check valve is the device that the drain hose is attached to on the dishwasher
Check Ball If the dishwasher won't drain the check ball might be stuck. The check ball is a small plastic ball in the check valve which prevents water from returning to the dishwasher after it has drained. If the ball gets stuck, it will prevent the water from draining also. The check valve is the device that the drain hose is attached to on the dishwasher.

The manufacturer has assigned this error or fault code to indicate a problem with the water circulation pump motor. Turn the appliance off for 30 minutes to allow it to cool. Then, restart the cycle. If the error code returns check the wiring to the pump motor. Also, if the wash impeller is broken this error can appear. If the impeller and wire harness check out, and the code keeps returning, you will probably need to replace the pump and motor assembly.

Bosch SHU runs even when the door is open, what do i need?


Hi Jeffrey,

This depends what you mean by "runs". If the dishwasher continues with a wash cycle - i.e. circulating water - with the door open, the simple answer is that you have a defective door microswitch.

However, I suspect what you perceive to be the dishwasher running, is actually the drain pump running continuously. This happens when the anti-flood protection system has been activated and continues even when the door is opened. The simplest way to check is to open the door (while it's "running") and pour some water into the tub. If the water drains away immediately, this shows the drain pump is running and the anti-flood protection has been activated.

This may be due to water having leaked into the base of the dishwasher, but it could be as simple as a stuck or defective float-switch.

Please try the simple test above then post back for further assistance. If you're planning to investigate or repair this yourself, you're going to need a Torx T20 screwdriver and a multi-meter would be useful as well.

Regards, BElectric

Does not advance to drain cycle


I would bet that it is the timer switch assy.
Motor runs ? yes
washes? yes
drain tube clear ? yes

If there is no drain valve to deal with, the problem must be the contacts during the timer cycle, since the main obviously works or you wouldn't be able to wash anything.
you need a new timer switch assy.
