SOURCE: what is error code 59 on a noritz tankless water

The 59 code is typically caused by insufficient gas supply to the unit. It can also be caused by obstructed exhaust flow, stuck exhaust damper (located directly on top of the unit's exhaust), insufficient makeup air, or improperly installed venting (i.e. too long or too many elbows).

I would recommend initially checking the incoming gas pressure at the gas connection on the unit. The gas pressure should not drop below 5" water column for a natural gas unit, 8" for a propane system (the unit need to be operating at its maximum output).

SOURCE: Noritz tankless water heater not producing hot water

I called Noritz error code 16 is a overheat problem. Noritz say's to flush your coil with vinegar or CLR.
Use a small pump to recirculate the CLR or vinegar through the system for 45 minutes and flush with fresh water. This worked for me.

SOURCE: Water Heater Won't Fire up

There are a few things you'll want to check:
1) make sure you have 120VAC at the outlet
2) measure voltage across the blue/white and black/white wires connected to the gfi (black box inside the unit on the bottom left or right hand side). You should read roughly 100 VAC on both sides. If you don't read voltage on the black/white wire pair, then you gfi is tripped. Look for moisture that might be shorting the gfi.
3) If the GFI checks out ok, you probably have debris clogging your flow sensor

a 16 error code is typically caused by scale formation. I'd recommend performing a descale on the heater.

What is code blinking 20 on noritz tankless hotwater heater N_069M


The error is a HIGH LIMIT THERMAL ERROR. That means Calcium buildup has appeared in the unit. It is also called scale. To clear the error you have to power it off. That is done by the circuit breakers. You should descale the unit first though.

Error 71


EC 71 usually means you are using a battery backup that doesn't produce a pure sine wave. OR you recently had a power outage and it shorted the circuit board. if you have a battery backup try unplugging that and see if it works okay. If not, just call Noritz for a replacement c/b.

Working on a N1321-ASME unit installed in a Taco Bell. Getting error code 21. Unit gas pressure is at 8.5wc and manifold pressure spikes to 2 when it come on but unable to see what it remains at because...


I recently had a similar problem with my N-132M-ASME heater. The unit would come on, then shut down and flash Error Code 21. According to the owners manual, that code indicates the unit is not getting enough air. I tried vacuuming the unit, blowing it our with air and checking to be sure the exhaust lines were clear. Nothing helped. A service technician came out and recommended I descale the unit and clean the burner. I did this but the problem did not go away. He also suggested I replace the Burner Sensor. It's not an expensive part, around $20. I ordered the part and have not had a problem since I installed it. Hope this helps.

I have a Nortitz natural gas water heater, model #N-063s-1. Acouple of days ago it stopped heating the water. what can I do myself to fix this matter. Thanks, lynnatheana@hotmail.com


There are many reasons a tankless heater will stop heating water. The first thing I would look for is a flashing red light on the burner indicator. The flash break down goes as follows

continuous blinking - typically means ignition failure or the unit is overheating; look for visible water inside the unit, have your gas pressure checked, or check the flame rod/igniter for buildup of debris

three blinks - typically indicates 16 error code; typically resolved by performing a descale

4 or 5 blinks - exotic error codes; for these you should definitely contact Noritz tech support

If there is no flashing light, first check your filter for debris. If the filter is clean, your flow sensor is probably stuck. Again I'd recommend contacting Noritz tech support to help you clean the flow sensor.

Error code 14 shows on the remote for a noritz tankless lpg water heater. what does it mean?


This means the thermal fuse has broken and needs replacement. The thermal fuse is a white cord which wraps around the heat exchanger. It typically breaks if the unit is excessively dirty and sooted. Before the fuse is replaced you should make sure the unit is cleaned with compressed air and descaled.
