Question about Hobart SR24-H Built-in Dishwasher

Open Question

Hobart SR24H Takes Several Cycles to Reach 180 Degree Rinse Temp.

Specifications call for a minimum incoming temp. of 110 degrees to produce a 180-degree rinse cycle. We have 112 degrees coming in, but it takes several cycles to reach 180 degrees. We ran the faucet for several minutes to circulate the hot water, and it still takes at least two cycles to reach 180 degrees,

SOURCE: rinse not hot enough

145 degree is just your hot water temp and that your dishwasher hot water booster is not working assuming that this machine has worked in the past to produce final rinse water above 180 degrees. Remove the bottom panel and to the right you will see the booster tank, look for a nickel size component with a small red button on it. Try pushing on it to reset it. If that does not work, check for voltage at your heating element on your booster tank. (the thicker wires) If voltage is present then your heating elements need replacing.

SOURCE: Hobart sr24h dishwasher won't get up to temp.

the water level is low (should cover the bottom of the tank about a 1/4")and the pump is starving - therefor probably not washing very well.

three things to check

1. check braided fill hose for kinks (you will have to pull the machine out if under a counter). run the machine while pulled out if possible to ensure its not kinking when you push it in.

2. pressure reducing valve-prv (if installed) on the incomming water line before the braided hose (probably under a sink). turn the screw on top clockwise to increse pressure.
TURN THE BREAKER OFF TO DO THE FOLLOWING!!
3. flow regulator (if installed) - installed under the bottom pannel at the end of the braided fill hose (about 2" long and silver). turn off water. you can simply remove it, drill out the centre or just remove the rubber peice inside.

inrease the temp by adjusting the thermostat on the right side under the bottom pannel in front of the booster.(dail is hard to see and breaker must be turned off)

remember - the machine must be turned on for several minuets to truly get up to temp.

Hobart ml 130017


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

Hobart sr24h; It is doing a double cycle; runs a compleat wash and rince cycle stops then 30 sec later start over so our normal 3 min clean now takes 7 min to fully stop operating. What could be the cause...


Thats easy....Change your timer !! The timer turns 180 degrees for one cycle .Then 180 degrees for another cycle thus completing a 360 degree rotation . One side of the timer appears to be broken.

Dishwasher takes hours to run through wash and dry cycle. what should normal cycle time be?


2 to 6 hours is possible. The newer machines have a water heat cycle that will raise the water temperature. lets say your incoming water is 90 degrees. The machine want to see 140 -165 depending on the cycle so that cycle will take 75 minutes to reach 165 (1 min per degree temp rise). multiply that by the number of wash and rinse cycles and it can run a very long time. Water should enter the washer at 120 degrees minimum. let it fill and measure the temp you will be surprised. Eric

Temp. too hot


First off, the temp adjustment can only be made by a trained service tech, since the dishwasher will need to be reprogrammed to allow for a lower temperature in the rinse cycle but still have the higher temp needed in the wash cycle. Also, since any change in the water temp settings will require a longer wash and rinse cycle to be programmed into the unit.

Of course, you could simply lower the water temp on the water heater that supplies water to this unit, but you'd have lower temp water elsewhere and likely get cited at the next heatlh department inspection on that issue.

Since this is a commercial dishwasher, you might want to reconsider lowering the temp, since health codes and standards for commercial establishments require a MINIMUM water temperarture of 185 degrees F (85 degrees C) for proper operation and to get all the crud off the dishes, etc.

Note, the manufacturer sets these units to the higher temp, 203 degree F (95 degree C) knowing that the water will cool down quickly once the wash cycle starts and the water contacts the dishes, etc. That is also why these units have a added heater element, to help keep the water at the correct temperature needed to both clean AND sanitize the dishes, according to established health standards.

If you really want to change the water temp settings, contact your Hobart service rep and explain the reason you want it lower and see what they say.

Hope you found this very helpful and best regards!

Just purchased a used LXIh4 temp on diplay only goes to 155F


The incoming water determines how fast the DW is ready for another cycle. For running continuous cycles, the incoming water will need to be 140 degrees. If you pause 2 minutes between cycles, the temp should remain consistent with a 120 degree supply.

Hobart lx 18 warewasher what hatco booster heater product compatable with it


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.

Hobart LX30H washing to hot.


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.
