My heater is dead, no lights, no nothing. I need help!
Of course there is no question here, so let's parse that line.
My heater is dead: (okay, call a funeral home)
No lights: (get fresh lights, candles...whatever)
No nothing: (double negative, meaning something)
I need help: (psychiatric, grade school level writing?..)
1) Is there power to your heater? If so, there are lots of protective switches to prevent the motor/compressor from starting and self destructing due to loss of refrigerant because of a leak. The "no lights" worries me that there may be a logic board (if your model has one) that is fried. My suggestion is to fill in the pool with sand and send the repair money to me...

This could be a water flo problem. you need to chech to be sure your by-pass valve is closed down enough to force water threw heater, There is a internal by-pass that could be a problem also, or a bad pressure switch. If the by-pass isn't the problem then you should check these also.

This reminds me of some of the High temp sensors ive replaced. I would start with checking the pumps flow to the heater. Make sure there are no abstructions and at least 35 GPM (gallons per minute) running to the heater. If your flow is too low, you will trip the high limit sensor after a short while.
This could also mean you need to clean out the heat exchanger. When an exchanger gets dirty, it blocks the flow of water, slowing it down and "super heating" itdue to the water being in contact with the exchanger for too long. This will also trip the high limit and call for service.
If both the above items check out, contact me @ [email protected] and I will guide you further.

Error code E05 can be caused by many failures in several places. The owner's manual has a decent flow chart in it to help diagnose where the trouble lies. You will find it on page 43 here...

Identifying problems with an electronically controlled pool heater is not a job for most homeowners without training and/or experience with this type of equipment. If you are unsure how to proceed no amount of tips from a site like this will replace experience. You may want to consider hiring a professional to look at your heater.
If you decide to pursue the repairs and need additional support please post as specific a question as you can as a comment to this reply.
