When I turn the hot water full open I get hot water for a few seconds then it turns ice cold. If I turn on the hot water half way I get hot water and it continues to give me hot water but when I add some cold water then the hot water turns off. Here is the craziest part of my problem.... the sink in the the same bathroom functions normally as does my kitchen sink! You can turn on the hot water full blast and you get all the hot water you want for as long as you want. How can this be??? possible pressure switch adjustment or check gas pressure also

It may have mineral deposit buildup on the inside. You will need to consult your maintenance manual to see how to flush the unit and clear it of deposits. You can also contact Insinkerator for the information as well. You can use vinegar to clean it just like you would a coffee pot. Take the inlet supply off and using a funnel pour the vinegar in and turn the unit on.

Usually when you are having a problem at only one fixture, and not any others it is a sign that you have a faulty fixture. Hope this helps.

I had the same problem with my Paloma a year and a half after installation...contacted Rheem\Paloma\Richman customer service (800-432-8373) and they recommened a local installer in my area. The technican diagnosed the problem as the "flow control valve"; he managed to get Rheem/Paloma to cover the part under warranty...I only had to shell out the money for the install.
