I neither confirm nor refute your words about Hobart playing ball. That water can cause a false water level reading by the probe set. The leaking water will run down onto the water probe's wiring and into the Molex connector. Over time, the seals in the vacuum breaker deteriorate and it will leak. Water flows through that vacuum breaker during the FILL and FINAL RINSE cycles.

Those hoses converge at a vacuum breaker several feet above the wiring. When looking from behind the machine, there are water hoses routed ABOVE the dual probe's wiring & Molex connector. If you've taken note of the dual probe that I'd previously mentioned…and its location, then this should be easy. This requires pulling the machine out from wherever it is in order to look at the rear of the machine. Something else came to mind that you should look for on that LXiH machine. Hobart 00-329274 PROBE, TANK WIRE | Parts Town FWIW: I've never had to replace the front probe to resolve an issue (yet). So…I suggest replacing the rear water level probe. In the end, replacing the probe had a 100% success rate.Īnyway, I RARELY tell anyone in this forum to outright replace a said part, but that's my suggestion. In weighing the cost difference between laboring over attempts to clean & revive an old sensor (which often DIDN'T help) – versus – the cost of a new one…was a push. Normally an attempt to clean them yielded no results, so I replaced them. I had many of those go afoul by sensing water when they shouldn't.

Sorta the same approach I'd learned years ago from trying to reconcile issues with Manitowoc ice machine thickness controls. In such a case, if cleaning it didn't work, I'd deem the suspect water probe to be “fouled” (my description) and simply replaced it. In doing so, I'd witnessed a LED illuminate before water level had reached it – thus revealing the problem. I've gone to the trouble of observing the LEDs on the board like I'd explained earlier.
