Rennai infinity water heat the temperature controller is blackked out - was working fine last night

SOURCE: washing machine doesnt heat the water

Most washing machines do not heat water, they merely let the hot water into the wash tub that comes from your house hot water heater.... when selecting warm, hot and cold water will be mixed together to get warm or when selecting cold.. only the cold water is allowed into the wash tub.. Please provide brand and model number of machine so I can tailor a reply toward your specific washer...

SOURCE: oven not heating

you could have lost one of your 120v leads to the machine. that could cause it to work only half way. go turn the breaker off and then turn it back on and see if that corrects the problem.

SOURCE: Cold water tap not working, house heating not as strong.

Okay let's trouble shoot this problem. The Hot water issue may just be that your Temp. control is not set as high as it was before it was replaced. Find the control on the water heater and check the setting. You can adjust it hotter from there, but it is not recomended to set it all the way to HOT. Just increase it at small adjustments and see if the water gets hotter. The Cold Water Tap issue.....Turn off the Cold and Hot water supply lines to the faucet. Remove the Cold water tap. VERY SLOWLY TURN ON THE COLD WATER SUPPLY and see if you get water coming out of the line. If you get water, then your line is okay. Inspect the valve to see if there is any debris in or on it. Clean and reinstall both taps and turn back on the water. It should work. Now if you turn the water on SLOWLY when the Cold water tap is removed, and no water comes out, Then you know you have an issue with the line going to the cold water side. (Frozen Line, Debris in supply line valve, Broken or Leaking Water Line) I hope this assists you........Joe

you can get it off the rinnai web site they have a spot on there to get the internet manuel,, but from what you are saying you may need to adjust the thermostat, or the temp, remember even though you will have endless hot water it still takes the smae amount of timed for the hot water to get to your faucet,, not only that make sure your shower heads aren't holding back to much water pressure, if you don't have enough water going thru the unit it will not stay lit, if will come on and go off, judt to dstisfy the unit,, make sure the filter is clear, on the cold side there is a cap screw if you take it off there is a screen in side you just pull it out and clean it and reinstal it,,
