Question about Water Heaters
The first time it went cold the display was flashing ''C4 76''.I pressed the power button and it went off.I pressed the power button again and it came back normal.The next time and every time after that when it went cold the display read ''C7 76''.The time it takes to go cold is getting shorter,now to short to take a fast shower! I took it apart and gave it a good cleaning after the second time it happend,but it didn't make any differance.I cant seem to find any physical or electrical reason for its trouble. I would appreceate any help you can give me.
Check the connections between the controller. try disconnecting it to see if that makes a difference. 76 means that it's either the PVC board of the connection between the controller and the tankless
