Sprayhead scaled on one or both stations
We descale each head and confirm an even spray pattern on both.

Decanter and airpot, one chassis
An NKT Combo down means either the decanter side or the airpot side has quit, and they fail differently. We repair both: warmer plates and brew valves on the decanter station, dispense seals and worn pump diaphragms on the airpot. Tell us which side is misbehaving and we bring the right kit to put it back in service.
We'll get back to you today.

Newco · Combo pour-over brewer
The Newco NKT Combo pairs a decanter station with an airpot station in one chassis. It suits operators who want warmer-plate service for the front-of-house pot and sealed airpot service for coffee that travels. From the bench that means two different wear stories under one lid: a warmer, decanter, and brew valve on one side, and a dispense pump, seals, and vacuum airpot on the other.

NKT Combo faults we diagnose
These are the NKT Combo faults we see in the field, split across the decanter and airpot sides, each with what causes it and how we resolve it.
We descale each head and confirm an even spray pattern on both.
The coil or diaphragm has failed. We isolate the station and replace the valve.
Element scale is slowing recovery. We descale and replace the element if it is degraded.
The inlet valve or level probe is lagging. We test both and replace whichever is at fault.
The element or switch on the decanter side has failed. We test and replace the dead part.
A grind or filter mismatch. We check both and adjust to spec.
Hard water builds scale fast. We descale and suggest upstream softening to stretch the interval.
Leak-by at the valve. We replace the seal.
A field swap. We fit a new decanter.
The seal on the airpot's dispense valve has worn. We fit a new seal kit, and if the vacuum chamber itself is breached it isn't worth repairing, so we quote a replacement.
The sensor has drifted. We compare it and replace if needed.
The tank is below setpoint. We check the element and thermostat and let it heat.
A restriction or a sticking valve on that side. We trace it and clear or replace as needed.
The pump diaphragm has worn. We service the pump and fit a fresh kit.
Scale on the probe is throwing the readings. We descale it, recheck, and replace if it is still erratic.

Updated August 2026
The dispense valve seal on the airpot has worn, or the vacuum chamber itself has been breached. We fit a new seal kit first; if the vacuum is gone, the pot is not worth repairing and we quote a replacement.
Yes. The pump diaphragm wears with use. We service the pump and fit a fresh kit so it primes and dispenses cleanly again.
They share a tank but have separate brew valves and warmers, so a fault usually sits on one station. We isolate the decanter side, find the failed valve or warmer component, and replace it.
A seized warmer thermostat is holding that plate full-on. We replace the thermostat before it ruins another pot.
More likely scale, on both sprayheads and on the element. We descale the tank, clear both heads, and replace the element only if recovery does not come back.
It adds the airpot side, so we look after a dispense pump, dispense seals, and a vacuum chamber on top of the usual sprayhead, valve, warmer, and decanter. Two hold methods, one visit.
Yes. Both stations run on inexpensive, available parts, and the airpot is itself replaceable, so almost everything that fails is a straightforward swap rather than a write-off.
Sprayheads, brew valves, the warmer element, a decanter, and airpot pump and seal kits. That handles the common decanter-side and airpot-side faults in a single trip.
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.
