Our Ultra-2 trips off when we switch to a sugar-free flavor. Is it broken?

Probably not. Sugar keeps a slush from freezing solid, so a sugar-free product freezes much harder and can overload the auger drive. The product has to suit the machine. We check both and tell you whether the drive is worn or the product is the problem.

Does EBMUD water scale up anything inside a Bunn machine?

Hercules gets EBMUD water, which is soft to moderate, so scale is rarely behind a problem in the product path. When a machine here misbehaves, we look at the refrigeration, the drive and the seals first.

How often should the barrel seals be replaced?

It depends on how many hours the machine runs and how carefully it is cleaned. Seals that are lubricated and put back correctly after each cleaning last longer. We check seal wear whenever the machine is open and tell you when a kit is due, before it starts leaking.

Bunn in Hercules

Bunn commercial service.

Hercules sits on the southeastern shore of San Pablo Bay, and its mild climate is easy on a frozen drink machine's refrigeration. When an Ultra-2 or Ultra-NX here starts straining, the cause is often in the barrel instead: a product mixed too lean on sugar, a drive that is wearing, or seals that have started to leak.

Our technician for Hercules is based in Benicia. The diagnosis includes a look at the machine running with your product in it. For Bunn connected to the building plumbing, the on-site diagnostic is $99, credited toward repair. We confirm countertop bench pricing when you book. We watch how hard the auger works, check the gear motor and the seals, and hand you a written quote before any work begins. CSLB #1136642.

Common repairs we handle.

Torque-out trips from a mix that freezes too hard. When a mix runs low on sugar, it freezes harder than the auger drive was built to turn, and the machine trips its torque protection. Staff tend to blame the machine. We check the product with a refractometer, then test the drive and the torque circuit, so you know whether the fix is a part or the recipe.
Gear motor bearing that grinds under load. A grinding note that gets louder as the barrel fills comes from a failing bearing in the auger or spinner drive. Caught early, it is a bearing and gear job. Run to failure, it can take the gear motor with it. We rebuild or replace the drive to match what we find.
Drip tray filling with product overnight. Product in the drip tray after close points to a worn barrel seal or a tired gasket at the front. We replace the seal kit and the gaskets together, then run the machine and watch the front through a full freeze cycle.
