Hi.
Try first disconnecting power cord or tripping the circuit breaker. Power reset can sort out a jammed control module.
If there is no inlet (no water getting in), then the pressure from inlet hose, the water inlet valve, and the overfill switch must be tested. Water valve is tested reading Ohms at valve solenoid. If the multimeter reads open (Ohms infinity), then the valve must be replaced. (
see here how to test). If valve is OK, then the overfill switch (float) must be tested. A way to test the float switch is by jumping its contact and starting a cycle. If all those parts are OK and there is NO water getting in, then the problem is the control module.
If the appliance does not even start cycling, there is noise, and there is water inside the appliance, then the problem is usually overflow detected. The noise is the drain pump starting from beginning of the cycle.
If
the dishwasher bottom looks dry either there is water trapped in the
corners or in the bottom panel, or the drain hose is set incorrectly,
and water is flowing back from the drain line, triggering the overflow
device. If there is no water and drain hose is fine you will check the
overfill device for faults.
Pull out the dishwasher and check the
drain hose height and elbow. Ensure that settings are as specified in
the user manual. If elbow height is incorrect you get water flowing back from drain inside the dishwasher. That is detected as overfill.
Remove the drain hose and put it in a bucket, then try
tilting the dishwasher 45 degrees backward, secure it safely (ask help
if needed) and start cycle, so that water trapped at the bottom can be
released. Put the drain hose to correct settings and put back the
appliance in place if this solves the problem.
If that does not help, then parts must be tested.
Check
the drain well again.Open the housing, and remove water present in there . The overfill switch is connected to
the float and can also be responsible of the problem. The switch
itself can be tested jumping its contacts or using a multimeter to
read Ohms at switch contacts. With contacts jumped no overfill will be
detected and machine will start working (stop cycle manually after machine begins filling).
Alternatively, remove the part and read Ohms while operating the float
arm. The switch must change from a couple of Ohms to infinity
(overfill) while you manually operate the arm.
If that does not
help, go for the rest. Do not replace parts without testing. Check again inlet
hose, check spray arms and impeller. Next step would be reading
volts from CCU (central control module), and eventually replacing the control module
Try first tilting the appliance and checking the drain hose.
Disconnect power before performing any maintenance operation.Regards.
