Office Cafina on the blink?
The Melitta Cafina XT4 brings the Cafina brew unit and milk system down to a compact, single-boiler machine built for smaller offices and light hospitality. We repair it the same way we do its bigger siblings: weak foam, a brew unit stalling on grind buildup, cold milk, an F-code that will not clear. Tell us the symptom and the wear parts come along for the ride.
We'll get back to you today.

Melitta · Compact super-automatic
The Melitta Cafina XT4 is the compact end of the XT family, rated up to 80 cups an hour. It runs a single boiler and the Cafina brew unit, with either the TopFoam module or the simpler OneTouch milk system depending on how it was specified. Smaller offices and light hospitality run it for full drink variety in a tight footprint. From the bench it is the same architecture as the bigger XT machines, just smaller, so it ages the same way.
Why Grajqevci

Melitta Cafina XT4 faults we diagnose
These are the Melitta Cafina XT4 faults that actually book service calls, with the cause behind each one and how we put it right.
A jammed or stuck brew cycle comes from grind buildup, worn cam followers, or a group drifted out of alignment. We pull the unit, clean the wear surfaces, renew the seals, lubricate, and confirm it cycles cleanly.
Grounds in the cup or thin shots mean a torn screen, a worn piston seal, or grind drift. We check the screens, fit a fresh piston seal, and recalibrate the grind.
A leak at the drip tray is usually the brew unit's lower seal wearing through after a year or so of cycles. We pressure-test the brew circuit, locate the leak, and replace the seal set.
Slow heat-up is scale on the element or an element starting to degrade. We descale, time the heat-up against spec, and replace the element if it does not recover.
Weak steam is scale in the circuit or a blocked valve. We descale the steam path and replace the valve cartridge if it is needed.
A descale alert that will not clear means the cycle did not finish or the counter was not reset. We confirm the cycle ran, reset the counter, and check the water-hardness setting against your supply.
A pump that will not prime, or drink volumes that wander, points to the inlet valve, a solenoid, the flow meter, or pump wear. We work the water path end to end and replace whichever part has failed.
Weak or patchy foam is milk protein in the chamber, a worn intake spring, or an air valve off calibration. We strip and sanitize the milk module, renew the springs and seals, reset the air-flow, and check foam density.
Cold milk is usually a failing temperature sensor or scale in the heat exchanger. We test the sensor, descale the circuit, and replace the sensor when it reads out of spec.
Off-tasting milk drinks point straight to a skipped daily clean. We deep-clean the pathway, swap the silicone line if it has stained, and reset the staff on the daily HACCP routine.
Twin-grinder dose drift is the two hoppers wearing at different rates. We weigh ten shots from each, measure the burr gaps, recalibrate, and replace burrs where they have worn past spec.
Grinder noise or a grinder that will not feed usually means a foreign object or bridged beans. We open it up, clear the obstruction, inspect the burrs, and clean out the throat.
An unresponsive touchscreen is a firmware hang or a hardware fault. We reset it, check the firmware, and replace the display module only if the panel itself has failed.
We read the error history, pinpoint the failing sensor, relay, or board, and replace it. Most F-codes are a single-visit fix.
A HACCP clean that will not complete is a misreading level sensor or a blocked return line. We find the stall point, clear it, and replace the sensor if that is the cause.

Updated August 2026
It depends how the machine was specified, because the XT4 ships with either the TopFoam module or the simpler OneTouch milk system. When you book, tell us which milk drinks you make and we will confirm the setup, but either way the milk-side repair is routine for us.
Weak foam is milk protein in the chamber, a worn intake spring, or an air valve off calibration. We strip and sanitize the milk module, renew the springs and seals, reset the air-flow, and check the foam density before handing it back.
A stalling brew unit on the XT4 is grind buildup, worn cam followers, or a group out of alignment. We pull the unit, clean the wear surfaces, renew the seals, lubricate, and confirm it cycles cleanly, which usually settles it for a long while.
The XT4 is rated up to 80 cups an hour, which suits smaller offices and light hospitality. If your floor is pushing well past that through the morning, you are into XT6 territory; we are happy to give you an honest read on whether the XT4 is sized right.
Cold milk is usually a failing temperature sensor or scale in the heat exchanger. We test the sensor, descale the circuit, and replace the sensor when it reads out of spec, then confirm the milk comes through at the right temperature.
With regular servicing, ten years or more is realistic. The XT4 uses the same brew and grinder architecture as the bigger XT machines, so it is durable; scale and skipped milk cleaning are the two things that shorten its life, and both are preventable.
Yes. A pump that will not prime, or volumes that wander, points to the inlet valve, a solenoid, the flow meter, or pump wear. We work the water path end to end and replace whichever part is at fault.
Generally, yes, because it is a single-boiler machine with fewer systems than the XT6 and up. The parts are smaller and there is no Steam Perfect wand to service, so a typical XT4 repair is at the lower end of the XT range.
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.
Tell us the model and the fault, and we will bring the parts.
