What type of detergent is not necessarily important - anything intented for use in commercial dishwashers should be sufficient. A restaurant supply store should have something suitable for you. Also, in case you don't already know, the LX30C is the non-booster-heater version of the LX30 (LX30H has a booster heater). Without a booster heater, you'll need to use chemical sanitizer. The LX30C should, hopefully, have a sanitizer pump installed to inject chemical sanitizer into the rinsewater stream. Most of these dishwashers also have a detergent pump to inject detergent into the wash tank and rinse aid pump for chemical rinse aid. If present, these pumps are located in the bottom of the machine. Remove the lower front panel (2 screws) and look for the small, black plastic assemblies with 2 hoses connected to each.
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.
Look on the top edge of the door to find the data plate. It sounds like an SR24, if the leds are on the left of two temp gauges. If your sanitizer pump has a tired silicone tube that is flattened from use, it will not draw chemical. if you have an air bubble in the sense board at the back, it will think you have run out. If you have changed the type of chemical or diluted it, the board will need recalibrating to suit. Put some sanitizer in a small vessel with the pickup tube and monitor the amount delivered. Usually one is looking for 50 ppm solution of bleach and rinse water.( test with litmus paper) If you have an SR24H with a booster, you don't need bleach sanitizer and holding the sanitizer button will turn the sense off.
what temp is it washing at. washing should not be the problem. This machine is designed to rinse at 180 degrees + to sanitize dishes. The machine could be converted to a chemical sanitize, it would use bleach in the rinse water instead of 180 degree water to sanitize.
I think you may have the wrong model number of the dishwasher.I work for hobart but i dont recall a dishwasher with the model number you givin me.Look on the data plate again some examples of hobart dishwashers are--sr24---am14---c44---c44a---lx18--lx30--lx40---lxi---uw50--sm6t2.Once you find the model goto this site and you will find a manual.any other questions let me know.http://www.hobartcorp.com/default.aspx
