LXiH rinse temp

[Tito]

I haven’t touched a LXiH in a long time. I believe that uses chemical to sanitize and not water temperature. I don’t remember seeing a rinse thermostat on this unit.

We would have to have the ML# to know what model and set up you have. But booster temp has no effect on the anti-syphon valve leakage. It is normally due to calcium particles in the valve either preventing it’s full closing or seating. It is a normal maintenance item to disassemble the valve and soak it in a acid like vinegar or descaler. Not knowing you water hardness can also be a factor as it is necessary to clean the booster periodically. They always build up scale ant the particles break loose. This causes restricted flow in the rinse wand partially blocking the nozzles.

I would start by cleaning the rinse nozzles and vacuum breaker. How old is this machine?

There is another possibility, that’s the incoming water pressure to high or the water solenoid valve leaking. But still, the rinse wands should be draining fast enough for that to not be a problem. Also check that the rinse agent chemical pump is set correct and only running during rinse cycle.
