Error 4 refers to a drainage failure

This could be caused by blocked filter, jammed pump, blocked hoses, or damaged pump

Hi
The dishwasher is not holding water so I suppose the pump is working. Once I clear the error and start it the error will come back up about 4mins later

If you start a drain of the appliance, then fill the tub with an amount of water, is that water then getting pumped out?
