Duane Dziewit Posted August 2, 2023 Report Share Posted August 2, 2023 Jet pump is short cycling (pulsating). Replaced the start capacitor and the problem continued. Replaced with new pump and the problem still remains. Vould the control panel cause this or the mother board. Q2000 system... Quote Link to comment Share on other sites More sharing options...
ratchett Posted August 3, 2023 Report Share Posted August 3, 2023 Try removing the filters, does the problem persist? Can you get a video of the cycling? This doesn't sound common for Hotspring, I haven't heard of this one before in the forums lol. Quote Link to comment Share on other sites More sharing options...

Just short cycles or pulsates. Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted August 4, 2023 Report Share Posted August 4, 2023 Test voltage to the pump. If it is also short cycling it's likely a transformer. If not, it's the centrifugal switch or start switch. Quote Link to comment Share on other sites More sharing options...
Duane Dziewit Posted August 4, 2023 Author Report Share Posted August 4, 2023 Had to reseal the heater and refilled the tub. Ozinator, Recirc pump and heater are working and operational. The LCD display appears to be faint and distorted (partly due to water being under temp). 20230804_145717.mp4 Ran jet pump and continues to short cycle/pulsates.

Duane Dziewit Posted August 5, 2023 Author Report Share Posted August 5, 2023 Is the centrifugal switch and start switch on the mother board? It is putting out 12v. Quote Link to comment Share on other sites More sharing options...

The water temp has nothing to do with the lcd. 13 hours ago, Duane Dziewit said: Is the centrifugal switch and start switch on the mother board? No, they are pump motor parts, and not the issue it seems. 13 hours ago, Duane Dziewit said: It is putting out 12v. To the pump? Next to the lights is a plug labelled "pressure". Turn off power, jumper this (connect the two wires at the plug with a small wire or foil) and try again. If it works, leave it. If it starts having a different error let me know. If it behaves the same... Disconnect pump 1 wiring from circuit board and see if it continues to click when you press the button. -If so, check controller wire and connections for shorts. Remove circuit board and check the back for burns or debris. At this point we have reached the test parts stage, where you need spare parts to swap out to test if it is the board or controller. -If not, test voltage to the pump terminals (labelled "jet 1" on the board). Post results. Quote Link to comment Share on other sites More sharing options...
Duane Dziewit Posted August 5, 2023 Author Report Share Posted August 5, 2023 Had 120v on the board when I disconnected pump and activated jet button. Reconnected terminal connections and had the same result. (Short cycling) The mother board does not have a light plug. Do I need to jumper the pressure switch? See screen shot. The pressure switch is built/wired into the heater. Quote Link to comment Share on other sites More sharing options...

RDspaguy Posted August 6, 2023 Report Share Posted August 6, 2023 I was talking about the led indicator lights on the board. Yes, jumper the pressure switch. If it continues to short cycle, turn off power and disconnect the pump wires at the bottom left of the circuit board labelled "jet pump 1" and try it again. See if it still short cycles the board by the flashing led lights on the board. We are trying to determine if the issue is flow related or control related. Follow the steps listed in my previous post and let me know what happens. Post pics (still pics, not video) of the equipment area and circuit boards.

Duane Dziewit Posted August 6, 2023 Author Report Share Posted August 6, 2023 I disconnected the pressure switch from the board and checked the resistance and the reading was .5k ohms. Checked output voltage on the board 5.2vdc. Tapped the heater end where the pressure switch is located a few times. Started the pump on the third attempt the jets started. Repeated many times and jets started. Problem resolved. Thanks again Quote Link to comment Share on other sites More sharing options...
Duane Dziewit Posted August 6, 2023 Author Report Share Posted August 6, 2023 BTW the tub temp is currently at 107F when set at 104F. . An obvious overshoot buy 3 deg F. Set the t/stat to 101F and tem is declining. Any thoughts you can share? Quote Link to comment Share on other sites More sharing options...

Mike223 Posted August 16, 2023 Report Share Posted August 16, 2023 This is easy - you have crippling line loss. Check your GFI plug end. Verify the spa is on a dedicated 20 amp circuit and the wire size is appropriate. NO extension cords. Pumps take the most energy to start running. You simply don't have enough voltage (due to line loss) for the motor to start up. Been a HotSpring tech for 16 years and I have seen this countless times.
