Question about EuroTech 24 in. EDW154E Built-in Dishwasher
On a EuroTech EDW154E dishwasher Service question:
What causes error messages Er1 and Er4? Dishwasher sometimes starts and stops repeatedly?
Eurotech Dishwashers are notorious for the E1 and E4 faults. The problem is with the solenoid they use for filling the dishwasher. The problem is something called the "Venturi Effect". The Venturi effect is the reduction in fluid pressure that results when a fluid flows through a constricted section of pipe. The fluid velocity must increase through the constriction to satisfy the equation of continuity. while its pressure must decrease due to conservation of energy. The gain in kinetic energy is balanced by a drop in pressure or a pressure gradient force. I know, a lot of big words. To put it simply, the orifice within the solenoid is smaller than the inlets and outlets. Even more simply put: Not enough water is getting into the dishwasher. It's a design flaw and I'm not certain there are many ways around it. Just make certain that you have a good water feed to the dishwasher (no kinks, valve on completley etc.). One thing you may try is reducing the feed pressure (i.e. slightly turn down the water valve supply to the dishwasher). Doing so may diminish the venturi effect by equalizing inlet pressure. It's worth a try.
