Question about Hobart 24 in. LXIH-3 Built-in Dishwasher

Open Question

Hobart commercial dishwasher LXiH ml-130017 is leaking water. How do I fix it?

Water is leaking out of top of the soap regulator. It is the regulator that regulators the ammount of soap that goes into the dishwasher and also it opens again to dispurse water with chemicals. I believe it only opens twice, just for the soap and the chemical water cycles. We don't know if we need just a washer or if we need the whole part and if so, what it is actually called.

hi there have you checked that the drain pump is pumping out the water fast ehough, sounds like you may have a blockage problem and the programe is timeing out ie. not draining within the specified time, for example 3 mins

SOURCE: Dish washer over filling?

The first thing you should do is clean the level probes in the unit. There are two probes sticking through the back of the unit and the water completes a circuit between these two telling the machine when it is full. If they are clean, you may have a faulty sensor or wiring.

SOURCE: pressure release keeps draining hot water

The 1/2" drain line you are referring to is probably the 3/4" line from the booster heater located to the left of the pump motor. The temperature/pressure relief valve is bad.

The booster heater could be overheating (bad thermostat), or you may not have an expansion tank on your building hot water system. The heating and explanding water in the booster has no where to expand to, causing a pressure spike high enough to pop the valve.

First, change the valve. I use a heavier-duty Watts XL40 valve, I purchase them from International Commercial Supply or Johnstone. Even if there is a cause for them to leak, once they start leaking they need to be replaced.

Once the new valve is in, power up and test the unit. Power up and fill the unit, then let the booster recover until it cycles off. Run a cycle, and check your rinse temperature. I like to see 190-192 degrees. If it went higher than 195 I'd turn the thermostat down. If it didn't shut off at all, and the relief blew, time to replace the thermostats in the booster heater.

There is a temp booster on that unit. A rinse temp of 190 is not out of the range of specifications. If it is too hot, you should adjust the incoming water temp

Commercial dishwasher needs a repair. The water heater booster rusted out, leaks and needs to be replaced with a new unit. Need a repair company that works with the State.


You can order a new booster heater.... I would just need the size of the booster heater itself in order to price you one.... What state are you talking about? Susan Restaurant Equipment Outlet 888-542-5959

I have a LXiC Hobart dishmachine I do not want to use Sanitizer because my hot water is very hot. How do you disable the sanitizer pump and alarm? H.


Do you realize that to sanitize with hot water alone requires 180 degree F water? I am a hobart technician and I've never seen any business or residence with hot water anywhere near that. Residential hot water is generally approx. 120, Commercial locations generally use approx. 140, but never near 180 (tap water that hot would be a severe safety problem). Hobart LXIH machines use a built in booster heater to boost the temperature of the incoming hot water up to the required 180 deg.

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.
