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-
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.
What's Included: E5 Circulation Pump with power cord
Description: This SilentFlo E5 circ pump replaces all previous versions of single speed and two speed circulation pumps.
The new E5 replaces the Watkins SilentFlo® 5000 and Silentflo 5002 circulation pumps on all Hot Spring, Tiger River & Limelight spa models from 1986 to 2015. The E5 was introduced in March of 2008 as the premier upgrade/replacement circulation pump and has had a handful of updated and thoughtful revisions since. The compact size and flexible positioning (can mount on its side or vertical on the sidewall of the equipment compartment) has won it favor with Hot Spring dealers worldwide. This little jewel uses less electricity and moves more water per minute than all previous Silentflo pumps. When you refill your spa and power it up this "next generation" magnetic drive, it slowly ramps up to insure that it's well primed with water. The position of the suction/inletis 1-11/16" from the floor which is the same as the Silentflo 5000 & Silentflo 5002. The return/discharge is 4-1/4" off the floor same which is also the same as the Silentflo 5000 & 5002. The impeller is accessible simply by unscrewing the top ring of the pump for easier cleaning if needed. This hot tub circulation pump draws water through a filter (1989 forward spas) and then pushes it through the heater, ozone injector (if equipped) and back into the spa through the heater return fitting or floor drain. It circulates twenty percent more gallons per minute than the Watkins Silentflo 5000 yet uses only 35 watts versus 65 watts by the Silent Flo 5000. Impressive!
Note: Some applications may require that this pump lay on its side for an easier connection to existing plumbing. It is not necessary to attach this pump to the floor of the equipment compartment.
Technical Specs: 115volts/60hz/35 watts (6,000 Gallons every 24 hours)

Installation of the new pump
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
