The Watkins 73039 No Fault 4000 watt PDR heater assembly can replace heaters in Hot Spring, Tiger River, Caldera hot tubs from 1995 to 2002.5 and more.

The existing 3/4" vinyl tubing and thermistors will connect with this heater.
A wrench may be needed to lightly loosen the termistors.
Typically the sensors go back in hand tight only but in some cases a lightly applied wrech is needed.

This is a PDR heater (power down reset).
Simply power down the hot tub, wait 30 seconds and the heater will be reset.
Tip: A heater that reapeatedly needs to be reset is often a sign of a bad heater or bad heater relays or both and should be replaced right away.

ATTENTION: This heater connects directly to the circuit board or heater relays.
It does not have a plug on the end of the power cord.
Hot tubs from 1995 to 1996 will need to re-use the old power cord plug and splice it into this new heater's power cord end.

If a red light is blinking on your hot tub, there may be a problem with the circuit board.
Give us a call and ask about getting your hot tub circuit board repaired.

ATTENTION: This heater does not use a pressure switch (no flow switch).
If your OEM heater has a pressure switch then you probably need the Watkins 76228 heater instead.

Series: No Fault PDR, IQ2020, IQ2000 (but not limited to, unless specified otherwise above).
