You need ot set the temp up higher, the temp it is showing you is what it is set at,, it is not a thermomiter, it is the setting, hold the up button in and the numbers will go up then you will get water at what the reading is

No power on unit/Remote Controller


try leaving the remote unplugged and unplug the unit for 10 seconds and plug only the unit back in. If you get hot water without the remote connected but nothing after doing the same thing with the remote connected then your remote may have shorted out. Otherwise your circuit board may have had a short. In which case, call Noritz for a replacement.

It sounds to me like you tried about everything I would. So I think you're already thinking about what I would do next. Try the flame sensor,and as last resort check all connection . Remove wires one by one clean and reattach. If all else fails change cotrol board. It's very hard to fix when it's not consistent. Good luck. Thanks

Hi .. if the thermostat is tripping and the safety valve is dripping , that would indicate that the water is being over heated , or the tank is at a low level . Check the thermostst setting, it should be about mid scale. Check the supply valve to be sure that there is a constant supply of cold water. Any thoughts?

Water heater needs a jump-start every morning


Hi,
Did they change the thermocaouple or the gas valve/thermostat???
My gues is that they changed the thermocouple and NOT the gas valve which also has the thermostat in it.

The gas valve is the problem... make them change that or give you a new hot water heater.

No hot water from bosch tankless heater


  1. If the display is blank, verify power to electrical outlet. (120VAC/60Hz properly grounded circuit required). Verify that the heater on/off switch is in the on (I) position.
  2. Verify the fuses in the control unit are good.To access fuses, the control unit must be removed. See BULLETIN TWH-G2-24 Two spare fuses are located inside lower access panel of control unit.
  3. Make sure cold water inlet connection is plumbed to the right side of heater when facing unit.
  4. A minimum of 0.8 gallons per minute (GPM) (3 l/m) is required to activate the heater. A quart container should fill in 20 seconds or less to activate heater.
  5. Clean inlet filter screen per chapter 5.2. of the installation manual.
  6. Inspect the water path for obstructions. Make sure all showerheads, faucet aerators and whole house filters are clear of debris.
  7. The heater activates when the water flow through the unit is at or above the required minimum of 0.8 GPM (3 l/m). A crossover creates back pressure on the water flowing through the heater. Therefore, a higher flow rate than normal is needed to force the heater to activate. To check for a plumbing crossover, shut off the cold water supply feed to the water heater. Then open all of the hot water taps served by the heater. Wait 10 minutes and check for water flow at taps. There should be no water flowing. Any continuous flow of water indicates a crossover is present and must be corrected. Consult a professional plumber for help in correcting a crossover. Failing single lever faucets and mixing valves are common causes of plumbing crossovers.
  8. With the ON/OFF switch turned to OFF (O) position and the power supply cord unplugged, remove theunit's front cover (See Page 5. Fig 3 of installation manual). Check wire connections between the water valve, control unit and electrode set. See chapter 9.2 of installation manual for location of these parts.

Model PTG-42PVN


According to the symtoms...sounds like you have a problem with the flow control valve. If less than 3 yrs old, contact Rheem Customer Support at (800-432-8373) and they can an authorized tech in your area to service the unit.

If the unit is out of warranty, I reccommend you still call customer support to find a local technician. Unless you're highly technical/mechanical, this is not a problem you should attempt yourself.

Thanks for trying Fixya.com
