How to Fix Rinnai Water Heater Error Code 10?
Fix 1: Check the venting system for any blockages
The venting system on the heater could end up with blockages due to debris. You can check for this by opening up the machinery and looking for any debris in the venting system.
If you regularly clean up the machinery, you can avoid the issue from occurring in the future. Make sure that you unplug the machine before you open it up to avoid any safety hazards.
Fix 2: The venting system is congested
Make sure that the venting system and the actual outlet vents have a place to breathe. If the venting system is congested, the heater machinery will not be allowed proper ventilation.
With improper ventilation, the heater will not be able to function as the flow of air is one of the most important things to get the heating system to work.
Fix 3: The fan motor is clogged
The fan motor is also an important part of the venting system for the Rinnai heater. It makes an important contribution to cooling down the heater so that the machinery itself does not get overheated.
If the fan motor has debris in it, it will cause issues with the venting system and can also cause the heater machinery to overheat.
Fix 4: The copper fins have buildup
The copper fins of the heater machinery could form a buildup of debris. With regular exposure to moisture, there could also be corrosion for the copper fins. This corrosion could also cause buildup.
When you open the heater also look at the copper fins to find any buildup.
Fix 5: Check the gas pressure for the heater
There is a certain threshold for the gas pressure on the heater. If the heater does not have gas pressure set correctly, the heater will not function.
Check the gas pressure and look up the specifications of the model of your Rinnai heater from the user manual. You can also check this online. Make sure that the gas pressure matches the specifications.
Fix 6: There are insects in the heater manifold
The insects can find places to squeeze into the machinery and this can also cause blockages.
This mostly happens with the heater manifold because that is an easy place to squeeze in for the insects. So open the machinery and look for insects. Remove any if found and close the unnecessary gaps in the machinery so that the insects cannot re-enter.
Also, make sure that you do not seal the gaps for ventilation.
Fix 7: The intake pipe has collapsed Form sealant
The form sealant is an important part of the intake point machinery. If the form sealant is collapsed, it will cause leakages in the heater machinery.
This is a problem with the heater that can be a little hard to catch. This is because even if you decide to open the machinery and check, looking at the intake pipe will be the last thought on your mind.
Now that you know, take a look at the form sealant. Get it changed if it is collapsed.
Fix 8: Contact an experienced technician from Rinnai support
At this point, you should reach out to the Rinnai support team to get further help with the issue.
