Why is our KM making thin cubes?

Thin cubes usually mean a scaled plate, weak water flow over the plate or a harvest that starts early. On Vallejo water, scale is the likeliest of the three. We check the plate, the pump and the harvest controls in that order.

Can hard water damage more than the evaporator?

Yes. The same mineral load cakes the float, the water pump and the inlet valve screen. Left long enough, a descale turns into a parts list. Regular cleaning keeps it a cleaning. On this water, it pays to look at the plate at every filter change.

Do you also repair Hoshizaki prep tables in Vallejo?

Yes. Refrigerated prep tables and sushi cases use a thermistor in the discharge airflow that drifts with age, letting the unit run 6 to 8 degrees warmer than setpoint. We carry the calibrated part and check the coil and fan while we are there.

Hoshizaki in Vallejo

Hoshizaki commercial service.

Vallejo's water comes from Lake Berryessa and the State Water Project through the Fleming Hill plant, and it arrives on the hard side. A Hoshizaki KM cuber freezes that water on its evaporator plate cycle after cycle, and the minerals left behind build up faster than the manual's cleaning interval assumes. Cubes come out thinner, harvests take longer, and the float and pump start collecting the same crust.

The first sign is a bin that fills more slowly. When production drops about 20% below the machine's rated daily output, scale is the first place we look. Our technician for Vallejo is based next door in Benicia. The $99 diagnostic is credited toward the repair, and you approve a written quote before work begins.

Common repairs we handle.

Scale on the KM evaporator plate. Freeze cycles stretch, cubes come out thin and the bin falls behind. We descale the plate, the water pump and the reservoir with a nickel-safe cleaner, then time a full cycle to confirm the machine is back near its rating.
Noisy water pump around year seven. The KM water-pump motor wears its bearings with age. It gets loud at startup, then the machine throws an intermittent high-amp code. We replace the whole pump assembly, not only the motor, because the impeller cracks when the bearing goes.
Filter and cleaning interval matched to hard water. On Vallejo water, a scale-reducing filter and a shorter cleaning interval cost less than repeated repairs. We look at how much scale built up since the last cleaning and set the next interval from that.
