I am a service technician and have an ER5 error code coming up on my customers dishwasher and the washer is draining out the water. But as soon as the error code came up the dishwasher stopped, and wouldn't start to work again. So I need to know what error code ER5 means? Can you please either let me know or at least know where I can get information for this error code. Thank you

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.
