Great Lakes Spa Pumps
Great Lakes spas used different spa packs and pumps over the years.
Troubleshooting the pump will depend on what the issue is:
If the pump runs but there is no water flow, there may be an obstruction in the line or a dirty filter, or air getting into the line.
· Make sure all valves are in the open position. (these can sometimes stick half-closed)
· Assure that the filter is clean
· Check suction intakes to make sure they are not blocked
· Assure the spa is adequately filled with water – a low water level will suck air into the spa plumbing lines and cause this problem
· Make sure jets are open – rotate the rings around the jets to assure water flow into the spa
If the pump is running and water is flowing, but the spa is not heating:
· Press the temperature set button to increase temperature so the heater will turn on
· Be sure service valves are all the way open
· Clean filter and check for obstructions
If the pump is loud or vibrates excessively:
· Check for loose screws on equipment module face and bolts attaching equipment module to spa frame
· Assure hot tub is positioned flat and not rubbing against any building part, deck or fence.
· If air is trapped in the pump, turn pump off, slightly loosen the pump unions and bleed air out of pump housing.
· Make sure that the hot tub has been installed on a flat and properly supported surface.
