Any ideas what could cause this

Hi there,
I have had an above ground pool for what will be the third year, I live in Ohio so the pool is only used 4-6 months. I have a Raypak heater 156 A. I was opening the pool and the heater fired right up and was working. I turn the pump off and there was a gurgling sound and it split the water hose going into the heater from the pump spraying boiling water into the air, I thought maybe it was a fluke and bought a new hose and it did the same thing. Turn the pump off, gurgling noise from heater and so much water pressure it split the line. I have attached picture. Heat exchanger had some minor build up on it but have cleaned. Not sure what else the issue could be???

Looks like it split at the seam. Was the hose left out over winter? I would probably try and replace the hose and turn down the heat to see if it works . Then if that is good turn heat up a bit and proceed .

Thanks for the response, it was not left out and I did replace with a new hose and it did the same thing. It is almost like the heater stopped taking water through.

Pool quality control. Might change to a better quality hose.
