Our Haier ESD210 will fill with water but not cycle. After the wash-program is selected and water drawn into the washer the three program-lights on the right-side will flash and then there is a beeping sound. When the beeping stops the original selected program-lights will flash. What would cause this? Thanks.

Not sure of the background on your fault, but this may help:
I have an HDW202. I accidentally opened the door while it was running - a no-no, but there is no lock preventing opening the door while it is running - not idiot-proof at all, disappointing, really. Anyway, closed the door, the washer kept running, then water started to leak out the front door. I quickly turned it off, mopped up the water, and turned it back on. It pumped out the remaining water visible in the bottom, then started flashing lights and doing 10 beeps in a row, pausing for a minute, 10 beeps in a row again, etc. - it was stuck in this cycle. I tilted the unit forward, backwards, and side to side, while turning it on and off periodically to check for results. More water came out of the unit, and it started to behave normally while tilted, but not level. Eventually, after more tilting, it returned to normal behaviour when level. It seems it did not pump all of the water out initially, and this was causing it to malfunction until all of the residual water inside had drained onto the floor from tilting the unit.

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.

Have the same problem with mine and have found no solution in the manual or web. four lights flashing and beebs ten times every ten seconds, water coming in and draining out constantly, very frustrating!

Since mine does the very same thing, it's my guess that is the sterilising cycle as by this point it has already washed, done a short fill to remove any remaining detergent, and two rinses. I'm also assuming the second short fill is just to cover the heating element and/or to to generate an amount of steam having being heated by the element (I'm basing that assumption on the heat of the dishes at the end of end of the cycle and the heat of the water when it drains)
