Fault code "i20" means water drain time-out.
(The pressure switch does not return to EMPTY after two drain phases lasting 120 seconds).
Possible causes:
Drain circuit obstructed/blocked; drain pump interrupted or jammed (foreign bodies); level pressure switch blocked on FULL (1-3); hydraulic circuit of pressure switch obstructed; wiring faulty; circuit
board faulty.
The floor of the machine is held with screws at the front, and clipped in at the back. It contains the bosses for the overflow water and the flooding switch.
After removal you come to the most important functional components.
In your case occurred intervention of anti-flooding system.
Displayed Error is "i30"
The cycle is interrupted and the drain pump switches on.
Could be:
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.
First, try to tilt dishwasher and see if leaking water from its bottom.
This is most commonly occurs.
Dishwasher is in fault mode hold start/pause button for a few seconds this will reset the unit run your cycle again if dishwasher faults again call you local service man.good luck
HIGH TEMP WASH- HEATED DRY- HIGH TEMP WASH- HEATED DRY - CANCEL/OFF
the control will be reset...but more importantly how many times ina row does the light flash..it will indicate what error code its displaying??
example if it flashes 4 times then a pause then flashes 4 times again its displaying the error code#4 7 flashes then pause then 7 flashes its displaying the error code#7 ect ect
This is due to the water not heating properly. I have put together some instructions on how to reset the control so you can use the dishwasher again and what to check for as to why it failed. Follow the link and let me know if it was helpful.
Check inside the diswasher to make sure that the bottom screen is clear of any debris. If clear on the last rinse cycle add a pot of hot water to the dishwasher and observe to see if your dishes come out cleaner.
If the come out cleaner you are probably not getting enough water into your dishwasher.
Replace your water inlet valve.
The dishwasher should heat the water to about 55 C as the heating cycle starts.
In these cycle, the dishwasher pauses after has filled with water and wait for the water to reach the temperature.
If the water isn't being heated (because of a problem with the heating element or thermostat), after the unit stops at the heating cycle, it never continues. Another possible reason is that the timer unit is defective.
If you have observed anything different post a comment.
I think I had a similar problem to this. It seems like it was starting a cycle but then it just stalled and made a buzzing noise and it did not drain properly. I opened the bottom of the dishwasher where the draining pump was located. take off the plastic cover and I found bits of broken plates were jamming the fins on the pump... Try this and see how it goes.. Hope it was of some asistance.
