My heater Hayward H400 is stuck in spa mode, buttons do not respond any more, so I'm assuming that keypad bezel is possibly broken.
I looked online and this keypad bezels are quite expensive, between 200-300 dollars.
1. Are they difficult to replace ,
2. And If i decide not to use heater at all, what will happen if I completely disable power to the heater, and just let the water pass through, since in past two years I haven't used heater at all.
3. What is the easiest way to completely shut off heater, maybe disconnect it at the fuse box ?
I'm looking for anyone help if someone knows something about this few problems.
