Before Replacing: If your circ pump isn't moving much (or any) water through the system, there may be some easy fixes.
• Is your heater reset button tripping or your red power light blinking?The #1 cause of this nuisance is low water flow through the heater. The #1 cause of low water flow is clogged filters. Even if they look clean!From 1989 forward, all Hot Spring and Tiger River circulation pumps draw water from a single filter. If that filter hasn't been chemically cleaned (recommended every 3 months) then the circ pump may not be able to drink enough water per minute. Once it draws water from the filter it then pushes it out to the heater. A semi-glogged filter causes that water to travel too slowly through the heater then overheats. The heater high-limit (heater reset button) or high-limit thermistor trips off shutting down the heater (and the jet pump & light on some models) because it thinks you have drained the spa and forgot to power it down. This safety device prevents a melt down (dry fire heater). To eliminate a clogged filter as the culprit, clean your filter(s) with an approved spa filter degreaser. There are two types of filter cleaners for spa filters, ONLY USE A DEGREASER. The other type of filter cleaner is for removing calcium deposits which is an acid type cleaner that will permanently set up any accumulated lotions, body oils and cosmetics on your spa filter(s) and ruin them! Filters should be replaced every 3-5 years.
• Is there any water at all moving through the system?If your spa has sat dry for any length of time, the circ pump impeller could just be bound up. We usually just tap on the wet end of the pump (the end where the vinyl tubing is connected) with a screwdriver handle. More times then not, this will un-stick the impeller.
