my friends dishwasher sounds like it's filling up. But then the water goes back out side to the drain. The dishwasher is bone dry & the panel starts flashing an f4 error. She has checked all the pipes ,no kinks or blockages. Do you have an idea how to fix it ?any help would be greatly appreciated

Hi Tracey,does the drain pump run so it flows out the waste hose or is it flowing out as it fills.If it flows as it fills,it sounds like the machine is syphoning.The drain hose will have to be shaped upwards if under the sink or pull upwards if in a standpipe so it is not sitting in the wate.
If the pump comes in and drains after a few mins,then it could be that the machine is leaking underneath and this brings the flood error in.All the best.
