Where is the booster located on the hobart am 15

If your Hobart AM15 dishwasher is displaying an AH error code on start up, it usually indicates that there is an issue with the booster heater. AH stands for "Booster Heater Circuit".
Here are some troubleshooting steps you can follow to resolve the issue:

1. Check the booster heater temperature sensor. It may be dirty or faulty, preventing the booster heater from functioning properly. Clean or replace the temperature sensor if necessary.
2. Check the booster heater element for continuity. If the element is broken, it will need to be replaced.
3. Inspect the wiring and connections between the booster heater and the control board. Loose or damaged connections can prevent the booster heater from functioning properly.
4. Check the booster heater relay on the control board. If the relay is faulty, it will need to be replaced.

If none of these steps resolve the issue, you may need to contact a professional technician to diagnose and repair the problem.

There are one or two hi-limit relays on the booster. One is on the front and if there is a second one, it is on the right hand side as you face the front of the unit. They are both manully have to be reset if tripped. Check them and also the booster's contacter

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.

Most of the Hobart LX series of dishwashers have their own built-in booster heaters. To check for one, remove the lower front panel (2 screws). The booster heater, if present, will be a stainless steel tank on the left side. If it doesn't have a built in booster heater then it was meant to be used with chemical sanitizer instead.

All Hobart dishwashers will have a wash tank heating element, but the rinse water is not heated by the dishwasher, unless it has a built-in booster heater. Usually a separate booster heater is used to heat rinse water to 180-190 deg. F for hot water sanitation.

It means that the final rinse thermistor is bad.Your not getting 180 degrees---right?Its located on the booster and costs about $65.I work for hobart.Any ?

The answer to this question will be based on the incoming water temperature that is supplied to the booster heater. The standard sizing for a booster heater is based off of a 40 degree F rise (140 degree F incoming water temperature) or a 70 degree F rise (110 degree F incoming water temperature). For a 40 degree F rise, a Hatco model C-5, S-5, or PMG-60 will supply the needed amount of rinse water for the LX-18 Hobart dishwasher. A 70 degree F rise would require a Hatco model C-9, S-9, or PMG-60 to supply the same Hobart model number.

A hatco C9 or C12 would be plenty big enough.I would use the larger kw unit if incoming water is very low,but it needs to be 140 degrees coming in so it doesnt sometimes trip the hi limit.

what heater,wash tank or booster and why?
