Water filter, inlet valve and solenoid replacement, the single most common cause of poor ice quality and low output on hard-water supplies. In Dunkeld this is sandton prime work on water supply side systems, attended within about 50 minutes of dispatch.On Sub-Zero equipment specifically — built-in refrigeration columns, wine storage and integrated units — the faults we see most in Dunkeld are evaporator fan failure in freezer section and control board and sensor faults.Every visit starts with a full diagnostic and a written quote before any part is fitted.Heritage overlays on some streets restrict visible external plant. Ice Machine Repairs bookings in Dunkeld are logged against Block 6 so we can allow for power availability on site.

Refrigerant data
| Gas | Classification | Suction pressure | Discharge pressure | Typical use |
|---|---|---|---|---|
| R134a | HFC (A1) | 80-140 kPa at -5 degrees C evaporating | 900-1 200 kPa at 45 degrees C ambient | Wine cellars, display cabinets, medium-temperature commercial refrigeration and some heat pumps. |
| R448A | HFO/HFC blend (low GWP) | 50-75 kPa | 1600-2000 kPa | Modern commercial ice machines, cube and flake units, coldroom retrofits |
Common questions
Can a built-in Sub-Zero be repaired without removing the joinery in Dunkeld?
In most cases yes. The units are designed to be serviced from the front through the grille and toe panel; full de-racking is only needed for sealed system work.
Do you charge a callout fee?
A standard callout and diagnostic fee applies and is quoted upfront. It is credited against the repair when you accept the quote.
Why is my ice cloudy or melting too fast?
Cloudy, soft ice means the freeze cycle is being cut short or the water is carrying too many dissolved solids. We test hardness and TDS on site, fit the right filtration, descale the plate and re-time the cycle so cubes freeze clear and hard.
Is scale really a problem for ice machines here?
Yes, it is the single biggest cause of lost output on this water supply. Scale insulates the evaporator, so the machine runs longer for less ice and eventually pits the plate. Regular descaling is far cheaper than an evaporator replacement.
