Hello. I have a Indesit Dis04 dishwasher. Recently it has started beeping repeatedly before the cycle starts and finishing cycles early without releasing the detergent tablet. When you open the dishwasher door, there is no heat and the crockery is still dirty. The only thing that has changed recently is that the waste pipe was blocked and the waste was not able to drain. The blockage has now been removed but it appears that something may have been damaged as a result. The problems have only started since the drainage problem arose and was resolved. Thanks in advance for your help.
Are you sure the water supply pipe isn't bent cutting off the supply, the bleeping noise you mention is an alarm to warn you of lack of water. Check that the supply pipe is ok and water is coming through it, then turn off the machine with the on/off button wait at least 20 seconds, then switch it back on again this will reset the machine, set the program and fingers crossed it will work.
there's a float mechanism inside that cuts off the washers operation if the waste gets blocked, that may have been damaged while ferreting about inside looking for the blockage, or it may be jammed and just needs freeing up,
