Spa overheating
1.
Why a spa overheats.
a.
Spas are designed to get hot and do not contain a cooling system.
b.
A spa can over heat if the outside temperature is hot, the spa is in direct sunlight, the filtration
cycle is set too high, or a possible stuck relay on the circuit board.
2.
Outside temperature/direct sunlight.
a. If the outside temperature is too high, it will heat the spa in addition to the heater within the spa.
b. To cool the spa down the mode can be changed to economy or sleep, the air valves can be opened,
or the cover may be left off for a short period of time to allow the excess heat to escape.
3.
Filtration cycle settings.
a. If the filtration cycle setting is set too high the pump will run more building up excess heat within
the cabinet of the spa.
b. This heat is then transferred into the water and overheats the spa.
c. Adjust the filtration cycle settings to f2 or fil2.
4.
Stuck relay.
a. When a relay becomes stuck on the circuit board for the heater it will not allow the heater to turn
off.
b. If this is the issue, when the pump turns off the heater will continue running and overheat within its
tube.
c. When this occurs, the spa shuts down and stops heating displaying a flow code. This is rare but can
happen.
d. If a relay is determined to be the cause of the issue replace pack.
Flow issues
1.
Determine extent of flow issue.
a. First determine if flow issue is with one individual jet, multiple random jets, or an entire section of
the spa.
2.
Individual jet/multiple random jets.
a. If one single jet is failing to flow properly, first make sure the jet is open by rotating it counter-
clockwise.
b. Note: the ozone jet cannot be closed.
c. If this fails to work there is either something stuck in it preventing flow or a kinked hose.
d. Inspect for kinked hose.
e. If hose is not kinked remove jet insert.
f. Once insert is removed any obstruction should flow out into the spa.
g. Return jet insert to spa.
3.
Entire section of spa.
a. For each pump within the spa there are two gate valves. Make sure these are fully open with
retainer clip installed.
b. If spa is equipped with a water divertor valve, make sure the valve is in the correct direction
allowing water flow to the designated area.
c. If the spa has more than one jet/boost button, make sure all pumps have been activated.
d. Check to see if the spa has a hidden jet/boost button. If so replace overlay.
e. If section of spa in question is connected to pump 1, inspect filter for cleanliness and make sure it is
free of debris.
f. If the filter appears to be expanding, cracking the top or bottom of the filter plastic, or the filter is
needing to be replaced more frequently then normal; inspect filter canister for proper direction of
flow.
g. The pump connected to the section of plumbing may have an air lock.
h. If the pump is failing to turn on at all see pump/blower not operating section.
