The SU-L and SU-H are older Stero undercounter dishwashers. The SU-L is low-temperature, and the SU-H is high-temperature with a booster, needing at least 110F incoming water and a 180F final rinse. The model numbers on the plate are ML-130239 for the SU-L and ML-130238 for the SU-H.
The display names problems in words, such as LOW RINSE TEMP, FILL ERROR, DRAIN ERROR and sensor messages that read open or short. The water supply and the door come first, then the probes, the level switches and the SU-H booster. Water leaves scale on the booster.
We have a page for each message on this site. These older machines are ones we repair, and we say so if one is not worth the effort.

What does the SU-H need for a good rinse?
It needs at least 110F water coming in, and it delivers a 180F final rinse. If your supply is cooler than that, the booster has to work harder than it was built to.
What do the on-screen messages mean?
They name the problem, such as a fill error or a sensor reading open or short. Write down the wording and call us. We have a page for each.
Do you repair older SU machines?
Yes. The SU-L and SU-H are older units still doing daily work, and we repair them. The cost is quoted first, and an SU past saving gets an honest verdict.
