One sprayhead scaled faster than the other
On the twin, the busier side scales faster, so one head fades first. We descale both and verify each pattern.

Two airpots, both kept full
When the CBS-72A drops a side, half your self-serve coffee runs dry while the other half pours fine. We repair this twin-station airpot brewer regularly: one head scaling faster than the other, a single station's brew valve failing, airpots losing heat unevenly, and cross-station quirks. Tell us which side and we fix it on-site, parts loaded.

Fetco · Twin-station airpot batch brewer
The CBS-72A is Fetco's twin-station airpot brewer, brewing into two pump-pots for parallel self-serve. It runs regular and decaf, or two coffees, at up to 15 gallons an hour combined, and offices and restaurants run it where one airpot is not enough. On the bench the twin layout means faults isolate to one side, scale, a worn valve, an airpot seal, while the two airpots wear at different rates because the busier one works harder.

CBS-72A faults we diagnose
These are the CBS-72A faults that book service calls, with the cause behind each and how we resolve it on a twin.
On the twin, the busier side scales faster, so one head fades first. We descale both and verify each pattern.
A brew valve that won't open is a failed coil or worn diaphragm. We isolate it electrically and replace the valve.
Strength drifting on one station is bypass seat wear there. We measure the split, reset the timing, and replace the cartridge if needed.
Drift on one tank is element scale or a thermostat reading off on that side. We descale, test, and replace as needed.
Slow fill on one station is the inlet or probe on that circuit. We test both there and replace the failed part.
A weak or tripping element is scale insulation. We descale and replace the element if it doesn't recover.
Overflow comes down to a grind or filter that doesn't suit the batch. We check both against spec and adjust until the bed drains properly.
Staggered descale alerts are normal on a twin, since the busier side scales faster. We descale both and recommend upstream softening.
A drip from one head at standby is that valve's diaphragm leaking past. We replace the diaphragm and seat on the affected side.
A station-specific controller fault points at one side. We read the status, confirm the station, and replace the part.
Scale on the probe makes the level reading wander. We descale it and replace it if it stays erratic.
When the two thermostats disagree, one has drifted. We compare both to a reference and replace the one that is out.
The busier airpot loses heat first as its dispense seal wears. We replace that seal kit and confirm it holds.
A stalling brew is a restriction or a valve fault. We find where it hangs and clear or replace as needed.
Cross-station behaviour is a wiring or relay fault linking the two sides. We isolate it and repair or replace as needed.

Updated August 2026
The busier airpot wears its dispense seal first, so it loses heat before its partner. We replace that pot's seal kit and confirm it holds, and if its vacuum chamber has been breached we recommend replacing just that pot.
Drift on one tank is element scale or a thermostat reading off on that circuit. We descale the affected tank, test the thermostat against a reference, and replace it if it is out of spec, leaving the good side alone.
It is normal, the busier station scales first. We descale both heads, focus on the affected side, and verify the spray pattern on each before reassembly.
Yes, cross-station behaviour is a wiring or relay fault linking the two sides. We isolate it electrically and repair the wiring or replace the misfiring relay.
Every three months or so at self-serve volume, and the two sides often alert at different times because one works harder. We descale both, reset both counters, and suggest softening upstream on hard water.
Yes. A failed valve is a worn diaphragm or coil, and on a twin it is isolated to one circuit. We replace the valve on the affected side and leave the working station running.
Usually. Sprayheads, valves, probes, and airpot seal kits are still available, and most faults sit on one side. We give you the repair number and an honest read on remaining life.
Yes. The brewer and both pots are serviceable in place, so we descale the tanks, rebuild the airpot dispense seals, and test both sides right at the counter.
Flat rate for the visit, parts billed at their actual cost on top. You'll hear the rate when you book, and for bigger jobs we quote in writing on-site before any work starts. No estimate that balloons mid-job.
Same-day. Call in the morning and a technician is usually on-site before the day is out; calls placed later in the day book for the next morning. Urgent breakdowns get priority routing.
The GTA and most of the Golden Horseshoe: Toronto through Mississauga, Vaughan, and Markham, out to Oshawa, Hamilton, and Niagara. If you're not sure you're in range, call and we'll tell you straight.
No. We work call by call. Plenty of customers put us on a maintenance schedule eventually, but that's their choice after seeing the work, never a requirement.
Parts carry their manufacturer warranty, and we stand behind our labour: if the same fault recurs, call us and we'll review it. Specific terms are discussed upfront on each job, not promised in marketing copy.
On-site whenever possible, which is most of the time. If a job genuinely needs the bench, like a full boiler rebuild or major electronics work, we'll say so before anything leaves your building.
Call us or send the form on this page. We confirm the machine, the fault, and a time window the same day. If it's urgent, say so and we'll route the nearest technician.
Diagnosis first: we confirm the fault, tell you what caused it, and quote the fix before touching a wrench. Most repairs finish in that same visit because the common wear parts ride on the truck.
High-wear parts for the platforms we service constantly ride on the truck. Anything else we order, usually next-day where suppliers allow, and we tell you the lead time before committing you to anything.
Usually, yes. We service legacy machines for as long as parts can be sourced, and we're honest when a repair stops making financial sense against a replacement. You get the math, you make the call.
Often, but that's not the pitch. We quote against the actual work, not a factory pricing book, and we'll tell you when a manufacturer warranty claim is the better route. Transparency is the value; the price usually follows.
Yes, and we do it by default on the way out. Half of repeat faults trace back to skipped daily cleaning or wrong routine, so the technician walks your team through what actually matters before leaving.
