dishwasher leak and water heater valve went, coincidence?

Hi,
I had a stange issue tonight, my wife started the dishwasher, and 15 minutes later, the kitchen was filled with water? I was able to see the leak was coming out of the door. I was able to suck the water out by moving the dial around until the water suck down. 90% of the water went down. I went in my basement to get my tools to see if there was any clogs and I noticed a good about or water around the hot water heater and the release valve pipe tip felt wet and there was water on the HWH around the copper pipe.

Could these two problems be related, could the dishwater leaked because of the hot water heater, or vice versa.

The dish washer is 6 years old and the HWH is about 9 months, yes 9 months old. The GE Water Heater was set to a setting of C. The settings go, A/B/C then VERY HOT. I lowered it to B for the time being.

Any help is appreciated.

Thanks,
RalphTrent

Greetings Ralph welcome to the Forum !

Gees, I just don't see how these two things have anything to do with each other.

I'm not sure if your Dishwasher fills only on a Timer, or if it has a Diaphragm to sense the level like a Clothes Washer.

Dry everything up, and watch both on continued operations. It'll probably happen again, and you can come up with more specific causes.

Thanks for the reply. After I cleaned up the mess from the dishwasher, I ran an entire cycle, and the problem did not happen.

This is what I am thinking and tell me if this is at all possible.

The water heater got do hot and it was going to release the pressure out the pressure valve as well as any outlet currently taken hot water, like the dishwasher. Does that make sense?

Ralph,

UMM, that's a stretch !

You shouldn't be able to set the Heater hot enough to pop the T/P. It should be rated well beyond what you can set.

I can't help but remember just in the past couple of days, where some other Users had a Surge Problem, and made the Heater T/P burp like that.

Just in case you don't know the generally accepted temperature (A,B,C don't tell you much) it safe to run it where at the first HW outlet/sink/whatever is at 120°.

That's considered the most you can take without hurting yourself, then the rest of the system is ok, because of the cooling the HW experiences as it travels through the Pipe.
Keep an eye on it, and let us know what happens.

Have a good Day !

"Could these two problems be related, could the dishwater leaked because of the hot water heater, or vice versa. "

Most certainly and here is the reasoning.

A dishwasher washer like a washing machine has a solenoid valve (quick closing) and sometimes if the water pressure is high enough and a valve (even a toilet fill valve) can cause a shock wave that causes water hammer and this sudden increase in pressure (shock wave) can cause the T&P to relief the excessive pressure (anything over 150 PSI).

Next time your dishwasher cycles have someone stand by the water heater NOT TO CLOSE and see if the quick closing valve caused the problem

well its been 2 days and since then the dishwasher has ran, with out leaking, 3 times. I put a bucked below the release valve tube on the water heater and it is still dry.

thanks for all the responses.
