  1. Jengen72: Each time you purge you are getting another layer of bio-gunk from the plumbing. You will win the war against biofilm. Keep purging. Start with hot water, add just what we say, no more. More does not do a better or faster job. Open all,jets. Let the foam build. Do not remove the foam while purging. Run 20-25 minutes. Wipe up all the brownish sticky stuff you see on the waterline, especially in the filter well area. Be sure to remove the filters as well. I assume you have read our directions. Let the tub set in the off position overnight without draining. In the morning, add one or two level teaspoons of the blue gel to the same water. Run the jets another 10 minutes. You should see a good delivery of more gunk. Drain, rinse wipe and refill. Balance the water and always add appropriate amounts of an approved sanitizer. Use the tub for a few more months before you do an additional purge. You may even go 6 months before you need an additional purge. Keep us posted as to how you are doing. The single most important thing you must do while purging is to wipe the gunk as it builds. Biofilms are comprised of sticky substances. Don't let the gunk that is released dry on the acrylic or you will work harder to remove it.

  2. Your pic is not available. Did you recently fill? Remove filter. Do have good flow from the return? That's quite a declaration. Please explain how you determined this. I am usure about the flickering, but the rest could ba a number of things. The flickering sounds like a shorting button in the topside, but if so would have nothing to do with the heater. So it maybe a fluctuating temp reading consistent with a sensor or heater issue. Or a power (main or low voltage) issue from a failing breaker or transformer. If you unplug the topside that system will run automated functions. Unplug it and see if it heats. If so, it's the topside. Everything else says air lock, faulty sensor, dirty filter, or power issue. Post some pics of the circuit board, wiring diagram, and equipment area. Loosen union nut on heater to bleed out any air. Check topside wire for damage from mice (very common). Test incoming power at the spa with a digital multimeter. Verify voltage is steady when heater is on and topside is flickering (bad breaker). Turn on spa light and see if it also starts to flicker (bad transformer). Remove heater and check for obstructions/debris. Unplug sensors and test with ohm meter set in 20k range. It is very hard to get the tester probes on the wires in the connector, but it can be done on the side of the connector. Post results. Always turn off power before reaching into that box to touch anything.
