CHECK 1 - Water Level
Ensure water level meets fill lines on both interior
sides of the spa. Check if this resolves the pump’s
malfunctioning.
CHECK 2 - Inside Connection Caps
Make sure the clear plastic connection caps have been
removed before turning on the pump.
CHECK 3 - Bleed Air out of Portable
Control Unit
If PCU makes a grinding noise, no water is going to the
pump. Bleed the air out of the pump by unscrewing the
Air Valve till water is released then re-tightening it. Check
if this resolves the pump’s malfunctioning.
CHECK 4 - Check Spa for Obstructions
Check that inlet/outlet ports inside the tub are clean
and remove any obstructions detected. Check if this
resolves the pump’s malfunctioning.
CHECK 5 - Check Filter Is Clean
Check the filter. If the filter is dirty or scaled wash and/or
replace it.. Check if this resolves the pump’s
malfunctioning.
CHECK 6 - Make Sure Connectors Are
Not Kinked
Check the connection hoses. Make sure that they are not
kinked or bent and that both the spa and the PCU are
set on the same level surface. If you still cannot solve this
problem, please contact us for service.
