The light on my Honeywell HCM-710 humidifier will not turn on. It worked great for about 2 months and suddenly the light quit coming on. I've cleaned the filter and also let the humidifier stay unplugged for 24 hours and it still doesn't light up. The fan will turn however the humidifier isn't producing moister. How can I fix this and what causes the blue light to not power on?
SOURCE: Not producing hot water
the only time it's the valve is when you loose pressure on the hot side of any faucet, depending on the age of it you could just call the company bosch and they will tell you how far away a real tech is from you and contact them for you, you do have a 1 year labor 5 year parts warranty with the tankless unit, for you I hope you are within your warranty,,,, if not change it to a rinnai system the will send people to you if you have a problem

You're probably in for a service call and/or possibly water heater replacement if unit is more that 5-6 years old.
Your water heater plugs into outlet. Check outlet with cheap circuit analyzer to make sure the unit is receiving correct polarity without line interference.
If unit is in the attic, then add more venting to soffit and roof so pilot is not being snuffed out by hot air. If unit is in basement, then open some doors and a window and see if unit needs more air.
Most gas water heaters require yearly cleaning and service.
Clean the combustion parts and tubes.
Clean the air intake.
Have gas company check gas pressure.

The problem can be bad gas control valve, air in gas line, low gas pressure, gas shut off handle not fully parallel with gas line, dirty combustion parts, lack of combustion air, improper venting. Or combination of all things. It's an electronic gizmo, anything can be bad or shorted, and repair may not last long.
Without a trained service technician to ohm-test the parts using correct service manual, then we are guessing at the cause.
Power vent water heater implies that you have side wall venting which must be replaced with another side-wall vented unit -or- it implies rapid reheating of water.
If water heater is more than 6 years old, you might be money ahead by installing a new one from local box store. Avoid the power vent and electronics. Local box store will have passive roof-venting type water heater BUT box store does not sell side-wall power vent. If your power vent goes up through the roof, then box-store variety gas water heater will work. Total cost $350 do-it-yourself for 40 gallon gas.
Or get 40 gallon 240Volt electric for $220 and connect to circuit breaker box. Requires no venting, and is easy to repair for years to come.
Or small 120Volt electric that plugs into outlet to tide you over until gas repairs can be made.
Look for scratch-n-dent models and always offer 10% off.

Shower uses 5-9 gallons hot water.
