Candy a8001 dishwasher

It could be a shorted solenoid or even the motor.

We have a Candy CDI2012/E-02 32900347 1330 3315 dishwasher from around 2013 that once stopped working about 3 years ago. A constant beeping signaled the problem after trying to initiate the washing cycle. Not remembering the details, replacing the controller card (~€50 ebay) fixed the problem at that time.

Now we had a problem again, similar to the one above. Once any of the programs was started, the dishwasher would first drain any remaining water (if detected any), then fill for a few seconds, then start draining/refilling again for about 3 times in a row until the controller detected there was something wrong. Again, everything stopped with a constant beeping. Replacing the controller card did not help this time.

There were actually two independent problems: We noticed that the inlet water hose was kinked. Thus, only little water would enter. Straightening the hose did not solve the problem, though.

We then thought it may be the flow meter. But it is extremely simple in this machine, turned nicely and did not seem to be the culprit.

However, we noticed some deposits in the water reservoir that also connects to the inside of the dishwasher. These calcareous deposits apparently clogged one of the channels. This may have induced some pressure difference, which the controller apparently interpreted as some water level problem. Unmounting the water reservoir with the built-in impeller, dissolving the clogging with toilet descaling agent solved the problem: the dishwasher is working again.

Actually, no electronic parts had to be replaced.

Could be the circuit board at fault

Check your water level to see if the water valve is even filling up properly. After starting the cycle, listen when the water fillup begins and ends. Open door and see if there is enough water at the bottom. Should fill up to the float valve. If there is not enough water, the valve needs to be replaced. Costs about $25 and can be replaced diy if you are handy with pushing back the hose clamp and undoing and redoing the water line connection.
Make sure you unplug the electric, and shut off the water before you even want to look behind the toe plate. Dishwashers have high electric hazard behind the toe plate..

dishwasher leaking from the door or from the bottom of the door is common problem and yes its advisable to get it fixed.but if its having any other problem other then leaking then it has to be checked first.but leaking problem is common it can be solved.first from which part of the door area the leak is occuring that has to be checked.
Some common leaking trouble makers....
Leaks at the door:
Door gasket loose/torn
Corner gaskets or door baffle/vent gasket
Door lock/latch loose/broken
Split spray arm
Over filling with water...usually the level is just under the heating element is normal
Something leaking through the door...like the soap or rinse agent dispenser gasket, silverware basket button.
Door hinge(s) bent
Wrong soap was used...dish sink soap instead of dishwasher soap
Rinse aid being used with mechanically softened water ( makes foam or suds inside the dishwasher )

Leaks from under the unit:
Look for whiting or calcium stain on the motor and pump assembly = motor and pump assembly seal leak...access panel removal help
Hose for upper spray arm split
Fill hose split or fill hose spout air inlet is calcium covered
Drain hose is split
Rusted liner...metal liners only
Fill valve leaking or allowing water to fill all the time
Heating element ends....where they come out through the dishwasher liner
Float or float gasket

Larry,
The float is generally for overflow conditions and will interrupt power to the fill valve solenoid.
If you are not filling completely in the time allowed by the timer, it is most likely a flow restriction in the water supply. Barring other obvious restrictions, the fill valve has filter screens on the inlet side of the fill valve, which is generally the cause of your symptoms. Be careful if you attempt to clean the screens, as the fill valves are very sensitive to debris, and can become stuck open if sediment gets past the screen. I usually replace the fill valve to avoid future problems.
Hope this helps.

It is coming from the fill tube. You can pull the unit out or use a mirror to look up underneath. It might have come off or got a hole chewed in it.

After reading a few of the other Haier models troubles, I pulled the unit out and tip it at 45 degrees backwards for around minute. Water pored from the back of the unit, once cleaned water up reinstalled unit and all seems to be back in working order.

i have adb1500 i have replaced all the board on front of door, and it leaks at the bottom of door.

Because you are not getting an error message, I agree that the controller card is malfunctioning. Almost everthing else would triger an error.
Recommend replacing the controller card.
