Rinnai Energysaver 1004FTR (nat gas) RED FLASHES

Hi, My spaceheater will run for a couple of hours then flashes both front panel indicator lights red, indicating air-filter cleaning required. But the filters arevery  clean. Turning off the economy mode alleviates the problem, but thats not suitable for constant running. No error codes appear.

The filter light can also indicate a build up of debris and lind behind the heater causing the blower to work harder to push out warm air. It could also indicate that the blower may need a cleaning or going bad. I will suggest that you pull the front cover off of the unit to inspect the blower which is located at the top of the heater. Feel the motor as it is running to see if it is hot. If so, you will probably need to replace it. I may have a used on so let me know. If everything in front looks good, pull the top trim panel off of the heater just behind the filters and inspect for dust. Clean with a shop vac. Hope this helps.

My Rinnai tankless water heater flashes 11 when calling for hot water.


Your Owner's manual should help. No manual, try MFG website, or email their customer service. Or try manualslib.com

Unit won't operate and there are 4 flashes on the red light.


Two things- Clean the sensor rods or replace(cheap and easy with YouTube instruction video) and at the same time replace the main program chip (also a easy plug in chip). The whole repair takes two hours for a homeowner and costs about 50 bucks for a chip. These are easy an generally the flame sensor rod is the culprit. The code may also be the limit switch but try EZ and cheap first. See You Tube..

Thanks for that mike, it is a worcester bosch combi 24cdi heating and water can stay on for an hour then everything goes off and the red light flashes. it will come straight back on when reset, but then...


Check the pressure reading, should be about 1 bar when system is cold. Various models in the range of 24cdi. If you do not have a manual, go to,
http://www.centralheating.co.uk/Boiler-Manuals/worcester-bosch-boiler-manuals/worcester-bosch-discontinued-boiler-manuals.
Get the manual for your unit, to wards the end of install manual it has a fault finder, Also has a basic 1 in the user manual. Number of flashes how fast the light flashes which one flashing can all mean different, So get the manual and check, Some parts are easy to fix, as long as you do not touch the gas side the rest is plumbing. Come back if needed.

Unit flashes the number 20


A 20 error code means the high limit switch is being tripped. This is most typically caused when scale develops in the heat exchanger. I'd recommend performing a descale on the heater to resolve the problem. Make sure to follow the instructions that came with your isolator valve kit.

Faulty Junkers water heater


first find out from your manual what the flashing red light means...that should narrow your search---could be a thermocouple shot,a rubber diphragm in the gas valve has weakened and not operated, or gas pressure into the appliance may suddenly be too low, or springs in gas valve may have worn out---very many possibilities

Flashing red light on Worcester 24i junior combi boiler


Pressure is ok? at 1 bar or above
I think on this one there should be a reset button [red] on the left hand top of the casing - or lower the control panel [ phillips screw on each side] and the button is on the left of the base plate. Press this and try the heating.or hot tap
P.S. if you're on a prepayment meter check you have gas.

Me too


1.Not an expert with natural gas furnaces.
2.Statements below are from my own personal experience, and knowledge from.

The red blinking light you see is on a computer control board. The flashes of the red light represent a type of code. Think of it as a Morse Code, if you will.

For example: Red light blinks three times rapidly, pause, then blinks one more time. This code represents a particular fault. (Fault = Problem)

There is a sticker, with a chart of codes listed for this red light. It is usually placed very near the red light.

A gas furnace should be repaired by a competent HVAC technician. This is not a device that should be attended to, by those who are not trained.
An HVAC technician will know where to look, what parts are needed, and if the gas furnace is safe enough to put back on line. (Safe enough to use)
