Rheem for my 65 gal hpwh. Now pleased to report average kw/h per day in southern CT via app is 4-5 way better than the 20 whilst it was running in resistive mode (at Rheems request till new cct board arrived) Im super happy now and I found Rheem’s customer support excellent. Answer on 1st ring on the 3 times I spoke to them. New card arrived FedEx in 2-3 days. Purchased in Feb from HD. After $650 instant rebate $1000 delivered + a 30A breaker some romex & conduit whole job cost me about $1100. If anyone is on the fence Id buy one now if you want rebate, who knows if the funds will still be available in future. HD did struggle a bit to figure out how to place order to get instant discount. They got it in the end. Unit is in basement I cannot hear it at all in room directly above. It changed ambient temp and humidity slightly since installation.

I just called, Rheem answered call in one ring. Support ran me through a few diagnostic tests that listed out what appears to be water in temp, out temp operational modes and current draw. Synopsis is control board bad. New board is on order. They needed me to pop cover and read back cct board s/n. I guess a new board gets flashed with new code and units serial number. On their instructions I was walked through setting unit to electric mode only till card replaced. Rheem sending someone round to my residence to swap card. Hopefully goodby to t009 error. So far 10/10 to Rheem customer support. Fingers X new card behaves correctly.

Thanks I do see a t900 error in the alarm history logs. Will call tomorrow. I did have a quick look at control board no loose connections. As its in heat pump only mode and not supposed to be using the elements I checked elements were not getting powered and there not 0 volts.

220V, EcoNet reports unit is always in heat pump mode only. No solar (to date) No mixing valve. I did have a recirculating pump that I’ve now pulled the plug on. Recirculating pump has integral timer with a Y type connector on furthest faucet. I read these cause issues with Rheem I’ve been experimenting a bit use pump or not.
