Question about Pool & Spa
SOURCE: i'm getting an HL1 reading
1-low water flow (this heater needs 45 GPM minimum to operate safely
2-blocked heat exchanger (flush exchanger through drain ports)
3-Unitherm Governor (already replaced)
4- Bad bypass assembley or bypass spring (these bypass assembleys do fail occasionally)
Id start with making sure the water flow is proper, and if that checks out ok, id replace the bypass spring and assembley.
Note: when examining bypass assembley, if spring is worn or missing, start with this only as its cheapest)
