["blinking Power Light" - Help]

The circ pump flow is good. I replaced the circ pump last week. The new one is conserably stronger than the old one was.

Problem still occurs

The last 2 nights I have removed the filter and reset the tub.

Problem still occurs- I wake up to a red flashing light.

I removed the cover (with spa powered and the Power flashing) and the 2 LEDs were not lit. The only light on the control box that was lit was the D17 LED.

Looks like I need to check the heater for buildup?

["blinking Power Light" - Help]

I have Tiger River hot tub- I am guessing it is an 02 or 03 model. The tub powers up then after a couple of hours the red Power light starts blinking and it stops heating. I reset the breakers and it works for a while and then the same thing happens. The more often that I do this the shorter the duration between the resetting of the breakers and the “Blinking of the Power light”. Maybe because the water is getting warmer in the tub? The tub never gets to the set temperature (maybe 10 degrees shy of it).

I tested the thermistors- they were still good

I have replaced both thermistors – same results

I force purged the tub with a garden hose through the gray standpipe- same results

I replaced the circ pump (The new one is considerably stronger) – same results

I double checked that I didn’t have an air leek or air bubbles in the circ pump.

The tub has a stereo- I have removed it and the its ac/dc convertor.

I have removed the filters and tested it – same results

If anyone has any advice on the next steps to diagnose this problem it would be greatly appreciated.
