I've recently had a problem with my gu1500xltb2 dishwasher where the water continue to flow to the point of overflowing. I've looked through your sight and came up with various parts which could be the area of concern. I've thought of the overflow switch, the water inlet valve. However, I'm not sure which part controls the filling of the machine. Can you help?

The water inlet controls the water off/on.
The control board controls the water inlet valve. It activates the valve for a preset time.
The overflow switch is a safety device. It cuts power to the valve if too much water is in the unit.
Odds are your problem is the water valve.
The best way to check is with a meter. Measure across it (voltage 120 volts) when it is filling.
When the control shuts off the power to the valve. the water should stop right away. If water keeps running for a while then the valve is not closing properly.
Could also be the control board if it applies power to the unit for too long. Unfortunately I do not know what that time is.
Another possibility is that the unit is not draining correctly so there is already water in the unit before it even starts to fill. In this case then the overflow switch will be shutting off the water. |

Thanks for the speedy reply. I was thinking the supply valve was the problem, but after looking at the site and seeing the overflow swith I thought it might have control of the inlet valve also. How long do the control boards usually last? Would the control board have an intermitten problem? I've had this problem in a lesser state about a month ago or is it still the valve.

There really is no usually it varies greatly.
Many never get changed for the lifetime of the unit.
