Sounds like you're referring to the vacuum breaker. It's very easy and cheap to rebuild, if it'll come apart - sometimes they're very difficult to unscrew the top and the whole vacuum breaker must be replaced.

Obtain a rebuild kit for the vacuum breaker from Hobart (about $5). Remove the screw from the top of the vacuum breaker and take off the chrome cap. Use a cresent wrench or channel lock pliers to remove the now accessible upper section of the vacuum breaker. Clean all scale from the brass piece you removed, particularly from the center pin and the surface at the bottom of the removed brass piece, where the threads start. This surface is the surface where the moving float's rubber seal will come up to and form a watertight seal. If you're unsure what surface I'm referring to, place the white plastic float onto the removed brass piece and take note of there the orange seal of the float contacts the brass - this is what must be clean, straight and flat to make a good seal with the new float. The center pin must be clean so that the float easily moves up and down on the pin without binding. Also clean all scale from inside the body of the vacuum breaker, although not as critical as long as the float will move freely inside the body of the vacuum breaker. Once it is cleaned, reassemble and you're done.

P.S. it's possible you may be able to stop the leak simply by disassembling and cleaning the scale as described above, but considering the cost of the rebuild kit, you should replace the float from the rebuild kit as the float's seal shrinks over time, which may in fact be your problem instead of scale deposits, or both.

Lxi hobart not pulling rinse aid i used a screwdriver across prongs on board to make it run manually but still not coming out

try replacing the "squeeze tube" inside the dispensing unit. Over time the tube flattens out. If the tube is flattened no chemical will be drawn from your jug.

Disconnect inlet and outlet hoses on rinse aid dispensing unit.
Remove 4 screws and pull off outer face of dispensing unit. You can watch the dispenser operate with the face off if you wish, as long as the hose doesn't fall out (which it won't).
Remove squeeze tube and install new tube.
Reassemble inlet and outlet hoses (be sure to not mix up which tube/hose goes on top and which on bottom).

Also possible that the hose from the chemical jug to the dispensing unit has a hole/crack or otherwise. If the hose has a leak it'll lose suction and draw air in from the leak and not pull chemical.

I have a hobart lxih that is leaking from the backflow valve even after replacing it

Make sure your flow pressure is 15 to 25 PSI. Flow pressure below 15 PSI will cause the vacuum breaker to leak.

Winterizing a LXIH Hobart dish washer

Joe - The main issue is that the builtin booster heater is full of water - it has to be drained - there may be a small drain plug (square-shaped head), if not, you may have to pull loose the heater element to drain the tank. I would pour antifreeze solution in there and also in the wash tank. Unhook the water inlet - you say the machine is hard-plumbed in but mfgr recommends using brauided water hose to connect to water supply. hopefully this helps - I service commercial machines and came across your question and maybe you can ansqwer one of mine - how do I cancel the "delime" indicator? I can't find operators manual. jimmy.

Hobart lx30 : rinse cycle

The rinse water in a LX30 is driven by water pressure. A solenoid valve, bottom front - gold body, opens up and allows the water to flow.

If you are referring to the rinse agent pump, there must be NO leaks in the tubing or the hose that runs through the pump. And if the unit has lost its prime, using your hand to "seal" it, and forcing water from the faucet into the line can prime it.

Good luck - Mike
