Question about Rinnai Water Heaters

Open Question

Clicking noise There is no hot water coming out of the tap. The Rinnai tankless water heater sounds like it is coming on, makes a clicking sound, and then turns off. The process starts over again. Alas, no hot water. What is the problem?

Its A Possibility The Left Over Water In The Hot Is Frozen. If Your Line Is Exposed Outside Somewhere It Can Easily Freeze Up. Turn On The Hot Water Everywhere In The House And If Accessible Check The Lines To See Where The Warmth Ends. You Can Leave One Off Over Night In Hopes That It Will Eventually Defrost.

What is the outside temperature? If it it is below freezing, you might have a frozen pipe. Using a plumber torch heat up the pipe, if it works, replace the insulation using a heavier layer.

SOURCE: I have a Rinnai model 2532 Tankless Water heater.

We had the same problem - the hot water would only be hot for 3 -5 minutes and shut off, then we had to turn the water off, wait a few minutes, and do it again. VERY FRUSTRATING.

Soution: The Rinnai serviceman showed me the heat-exchanger blower/fan: It was clogged with dust and moths.

Another clue: Our Rinnai was extremely noisy when the heat came on. After the fan was cleaned and replaced, it is nearly silent.

If you are reasonably mechanically inclined:
TURN THE BREAKER / POWER OFF to the unit.

The blower-fan is located in the lower central area of the unit (at least on our unit). If you draw imaginary north-south, east-west lines through the center of the unit, the fan is in the lower-left quadrant. There is a spring clamp securing the black rubber accordian-like tube to the fan. There are two screws that secure the fan to the unit. there are two plugs that connect to the fan, as well as a third air-flow sensor that should be removed. then you can look at the fan unit, as well as the grill on the underside of the heat-exchanger that should be cleaned.

My thought was to go out and get a simple bug-screen, and place it over the air-input outlet vent going outside, but the repair guy said that although it may sound good, if that screen ever gets clogged, or reduces airflow to the Rinnai, then the unit will work harder, or even shut off, giving the same problem. Also - the Rinnai pipe going outside is a pipe within a pipe - so its both inlet and outlet air.

Rinnai R85 starts to warm then stops and blinks 61??


I went to the Rinnai website and this is what I found for error code 61.
Error Code 61 Problem: Fan failure
Solution: Measure the resistance on the fan motor, check the damaged or loose wiring and connections. Make sure that the fan spins freely.
Sounds like either your fan is broken or something is keeping it from spinning freely.
Hope this helps.

It's scaled
Do you have a softener? Water must be 15 GRS/PPM or less in iron and calcium. Hot spots in unit are boiling water and are causing the noises.
Descale and flush unit following Rinnai Specs and check water hardness for compliance with Rinnai standards because too hard an inlet water will VOID the Heat Exchanger Warranty (10 year).

Rinnai RL94i - Produces hot water for 3 minutes, then stops


I just had this exact problem. It kept getting worse until we had no water. Our Rinnai tankless hot water heater started the same way though, with hot water for a few minutes and then would shut off with an error code 10. We just had to shut the hot water off and then back on, wait a minute or so and we had hot water back for a few minutes. Our unit would come on with a loud vibrating noise and remain until it shut off with an error code 10 (air flow fault). The solution was to remove the blower fan and blow out the squirrel cage. Ours had moths in it. We also vacuumed out the fan housing. Be careful to mark any wires you disconnect and take pictures before removal. Our unit is now almost silent when it comes on and supplies endless hot water.

Rinnai tankless waterheater does not begin heating water as soon as tap is opened,why?


Not sure what you mean specifically. Obviously the heater takes a few seconds to go through pre-checks and will then light. It will then take a few seconds for warm water to reach the tap depending on how far the heater is from the tap. If it is actually taking a while for it to light you need to make sure you turn the tap on full. These heaters need good water flow to fire up. Check for any filters in the tap ware and ensure they are cleaned out. I often take these filters out as they cause nothing but trouble and block too easily.

Rinnai Tankless won't stay on


how far is the tankless from the gas meter? error code 12 means it doesn't have enough gas running to it. is the 3/4 flex true 3/4 or is it 1/2 with 3/4 threads. have you checked your BTU load on your house to make sure your 1'' pipe can handle everything else you have on the house? sounds like to me you dont have the right amount of gas to the unit.
