Re: Dishwasher / Rattling Pipes? What's Going On?
The repair person might be on to something.
Dishwasher repair person looked at it and couldn't find anything wrong. He said it might be condensate from after wash OR that there might be leak in intake valve.
The valve he refered to is electrically controlled ---- called a solenoid valve.
These types of valves are quick acting and when water flows and then is quickly stopped creates a surge in the water pipe. It's this sudden surge that rattles pipes.
It may be that valve is chattering --- opening and closing several times instead of remaing open when it's supposed to which would cause surges in the pipe.
If it's also weak it may be passing which might explain why there is the cup of standing water.
It could also be high water pressure though this should also show up with other water usage and not only when the dishwasher is used.
Just a thought.
