My Raypak (model # P-M206A-MN-C) heater has two (perhaps related) issues that I would appreciate troubleshooting help with.
First, it is making periodic but regular noise, somehwere between a rattle and a knock. Here is a link to a video demonstration:

From reading other posts referencing a knocking sound, I understand a likely culprit might be a broken bypass valve, as TFP member Paul (ps0303) posted a helpful video about. Before attempting this repair, I wanted to upload a video of my exact noise to verify that this sounds like a broken bypass valve, as opposed to something else.
Second - and perhaps related - is the heater also seems to be inconsistent in staying on long enough to heat the water to the desired temperature. It kicks in and runs for a while, but then seems to prematurely shut down shortly thereafter so it is taking days just to get the water temperature up to the low 70's. I've backwashed a couple times to verify the water flow is good, and there are no physical heater bypass valves between the filter and the heater.
Any ideas on what could be causing this? A teperature sensor perhaps? Could this temperature issue be either a consequence of the above rattling noise, or perhaps related to it?
Thanks in advance for any helpful feedback.
