This is our first year with our new pool and we have used the heater about 5 times. The first 2 times were in late April, and when we tuned the heater on, it ignited within 3 - 5 seconds and had no issues. Recently, the past 2 times, when we turn the heater on, it takes about 3 minutes to ignite, unless, I turn it off quickly, and then turn it back on......it will then kick on within the 5 seconds. I have questioned this with Hayward and I am still awaiting an answer. Has anyone experienced this issue with this unit or similiar?
