Rheem Tankless Water Filter Cleaning

Helpful video! This fixed my P1 error code. Note that this video does not show the user bleeding the pressure from the line. When I did this I got a rush of water coming out of the filter as the system depressurized. I'd recommend you turn off the cold and hot, and then use the pressure release above the hot water valve. Grab a bucket just in-case you still have some pressure built-up in the machine.

thats the most yellow water I've almost ever seen

Shouldn’t u purge the air out before turning unit on?

it's a good video so long as you play it at 2x speed...

thank you so much!! our heater was not working at all. we have well water and the filter was pretty dirty. This helped immediately

I've had my heater for about 6 years and only just learned about this. However, I unscrewed the black plug and the filter mesh part is stuck inside. It spins around freely, but I just cant get it to come out. If I use force it will probably break the plastic surround part. Any ideas?

Rheem tankless water heater error 29

Excellent video with very clear instructions. A model for other instructional videos. Question: I have a RUTGH-95DVLN-2 model. Instruction manual says to drain the heater after shutting cold intake off. Is that not necessary? Thanks.

Awesome, thank you!!! We had water issues due to our main filter breaking down, but replacing the filter didn't fix the hot water pressure. I figured there had to be a filter somewhere on the heater unit, you saved me calling the plumber on a Sunday :)

What if there’s no filter

My hot water suddenly turned off tonight and the instructions in video did the trick. Thanks so much for showing how to fix it, I owe you a beer.

Thank you, youvideo was helpful.

Thanks!

That filter assembly does not seal with torque…the o-ring just has to be seated in the housing…so, turn the filter until it hits bottom…no need to use a wrench!

Very useful!

What is the fitting called that the filter screws into? I can find the filter but I can not find that fitting it seats into. Thanks!

How about if the the filter is stripped all to hell?

My filter was striped on the out side and striped in the middle. Someone tightened way to tight. I bought “The Tankless Tool” and it absolutely worked. I was able to loosen and replace my filter.

Now like $18+

I've used this excellent video several times to clean my filter. I always have the same problem: I take the filter to the kitchen sink and turn on the cold water to clean the filter. When I get back to the heater, lots of water has drained onto the floor. What am I doing wrong? TIA
