Why does the low voltage breaker kick off every time in turn the vacuum on?

Check to see if the ENTIRE suction system is free of debris. Empty your vacuum bag. Ensure that the brushes/wheels are moving and not jammed. Check for proper voltage to the system. If all of these items are ok, then it needs to be serviced.

This sounds like restricted fuel flow. Items suspect are pick up screen (in the tank), filter, hoses, and the carb itself.
You have to open it up to find out where the issue is.

Turns on but does not move.

Thank you for posting your question here on

Your problem could still be in the power supply, cable or motor unit. The motor unit is the most likely problem. For starters, try the tip I posted here on Fixya, found at:

If that is not enough, try our sites FAQ section on Dolphins at Select the FAQ button then from the drop-down select Dolphin. While your cleaner was made by Aquavac (Hayward) they work very much the same way.

It is not recommended you open the cord end that connects to the motor unit as you are breaking the seal for the submersible electronics. For information about sending your unit in for repair use the dolphin form link on the bottom of our site

Aquavac Tiger shark won't operate

The power supply powers on even when it doesn't output any voltage, so it's kind of misleading. You should have the power supply checked or you can do it yourself if you have a multi-meter, by measuring the output and making sure there is 24V.

Aquavac 42 tankless water heater: we cannot find a source for parts in US. Please help

Hello aknapton:
I just removed a working aquavac 42 from our home and upgraded. You can have the whole unit if you would pay for shipping.
It worked when we removed it. It was fussy about the standing pilot and had to clean the thimble jet a lot (dirty propane) but it did work. let me know.

Loud instant 2-3 second rattle around the under

Check all braces under your car. Not just visually, put hands on each and every brace. Sounds like one might be loose or broken. Hope it's as easy a fix as mine was.
