COLLECTED
Hopper, grinding head with its dial, spout and bag clamp. The burrs sit flat behind the dial, and the dial sets the gap between them.
SECTION 01 · WHY US
Four differentiators
02
Zero, then the distance detector
An E65 or E80 with new burrs is zeroed and its Disc Distance Detector calibrated, in that order, the way the manual sets it out. Then it is set on your beans.
03
The scale is treated as a scale
A grind-by-weight grinder is calibrated with a reference weight. It is never carried by the fork, and it goes back with a note on where it should stand: a counter that moves gives a dose that moves.
04
Original burrs, unless you ask
Mahlkönig states that non-original burrs void the warranty and can result in motor failure. If you want an aftermarket set in an EK43 we will fit it, and we will tell you that first.
Mahlkönig belongs to Hemro Group, with Ditting, Anfim and HeyCafé, and its US office is in Seattle. Two families do most of the work on a bar. The EK43 is the tall one: 98 mm burrs and one grinder for filter, espresso and retail bags. The E65 and E80 are the espresso grinders, and the W versions weigh every dose. A grinder that weighs coffee has a scale inside it, and a scale drifts in ways a timer never did.

SECTION 03 · COMMON PROBLEMS
What goes wrong on a Mahlkönig
- P-01
Shot times creeping on an E65 or E80
Burr wear, measured in kilograms and not in years. Mahlkönig USA rates the 65 mm set at about 800 kg at a medium setting, and the E65S GbW manual says around 700. A bar using 15 kg a week is there in about a year. The burr change is quoted against the set: the 65 mm set lists at $164.99, the 80 mm special steel set at $419.99.
- P-02 $150-$230
Humming, not grinding
The manuals give three causes: a clogged grinding mechanism, a setting that is too fine, or a foreign object between the burrs. The chamber and spout are stripped and cleared, and the burrs are checked for a chipped edge before the grinder runs again.
- P-03
EK43 motor runs, burrs do not turn
The shear plate. It is a small plate in the drive, made to break before the motor does if the burrs seize on a stone or a screw. The part is cheap and it is a listed spare. What matters is finding what stopped the burrs, because a new plate on a damaged burr breaks again.
- P-04
Breaker trips in the middle of service
The thermal overcurrent breaker, and behind it a motor protector that cuts out when the winding is hot. The manual warns that repeated tripping can damage the motor winding. The E65S GbW is rated for 4 seconds on and 26 seconds off on a 110-127 V supply. A grinder asked for more than that in a rush is working outside its duty cycle.
- P-05
Grind-by-weight doses wrong, or the display stays red
On an E65S GbW a display that stays red and will not grind means the scale needs calibrating. Doses that wander point to a load cell that has shifted, an unstable counter or a worn flapper. The load cell is damaged by lifting the grinder by its portafilter fork.
- P-06 $150-$225
Zero point wrong after a burr change
After new burrs the manual requires two steps: the burrs are zeroed, then the Disc Distance Detector is calibrated. Skip the second and the number on the display no longer describes the gap between the burrs.

One flat figure for the service, whichever Mahlkönig it is. Burrs are a part and are quoted on top only when the measurement says they are due.
MAHLKÖNIG · FIGURES
On the bench and on the bar.
Mahlkönig EK43, 98 mm flat cast steel burrs. Mahlkönig USA rates the set for about 6,000 kg of coffee at a medium setting.
The dial moves one burr toward the other. After a burr change the zero point has moved, and the scale means nothing until it is set again.

SECTION 05 · FAQ
Frequently asked.
Q-01 How much does Mahlkönig grinder repair cost?
A service is the flat figure above. One fault is priced after the diagnostic. Typical on a Mahlkönig: stripping and clearing a blocked grinding chamber $150-$230, zeroing and calibration after a burr change $150-$225. A burr change itself is quoted against the set, because the sets run from $164.99 for the 65 mm to $599.99 for the EK43. Typical figures, not quotes. What the repair costs depends on what we find. You get a written estimate before anything is done, and you can decline it — we bring the machine back and nothing further is owed.
Q-02 How long do EK43 burrs last?
Mahlkönig USA rates the 98 mm cast steel set at about 6,000 kg at a medium setting. A shop grinding 20 kg a week needs more than five years to get there. If an EK43 that young is grinding badly, look at cleaning and at the zero point before you look at the price of burrs.
Q-03 Are you a Mahlkönig service partner?
No. We are independent. Mahlkönig USA gives one year of warranty from delivery on a grinder bought from its store, and excludes unauthorized service and non-original parts. A grinder inside that year should go to Hemro in Seattle first. We work on grinders that are out of warranty and order parts from the US channels that stock them.
Q-04 Can we change E65 burrs ourselves?
Mahlkönig would rather you did not: the E65W manual says to contact your service partner for a grinding disc exchange, and the EK43 manual restricts maintenance to trained personnel. The screws are not the hard part. The zeroing and the distance-detector calibration afterwards are, and a grinder that skipped them reports a grind setting that is not true.
Q-05 Our E65 stops after a few doses when the bar is busy. Is it failing?
Probably not. On a 110-127 V supply the E65S GbW is rated to grind for 4 seconds and rest for 26. Back-to-back doubles for a long line push past that, and the thermal protection does its job. If it trips on a quiet morning as well, that is a fault and the motor circuit needs testing.
Q-06 Do you come to the bar, or does the grinder leave?
Your choice. A courier collects it and brings it back, and an EK43 at 26 kg travels without trouble. Or a technician comes to the bar, opens with the diagnostic and writes the estimate there. The flat figure above is the bench price. When we are already at your bar for the espresso machine, the grinder is serviced in the same visit at the add-on price.
SECTION 06 · CASE STUDY · HONEST OPINION
Typical call · how this fault usually goes
A typical call on an E65S GbW: doses that used to land within a few tenths of a gram now miss by a gram or more, and the bar assumes the burrs are finished. The bench starts with the scale. A reference weight goes on the fork and the load cell is calibrated. The flapper is checked for wear. Then the burrs are measured, and the kilograms through them are worked out from the bar’s weekly order. About an hour on the bench when the burrs stay, closer to two when they are changed and the grinder is zeroed again.
Honest opinion
The EK43 has a reputation that makes people replace its burrs years early. The set is rated for about 6,000 kg and lists at $599.99. That is ten cents a kilo, if you use all of it. A cafe that changes EK burrs every two years on filter volume is throwing most of that set away. Clean the chamber on the schedule in the manual, which is every 2 to 5 days, have the zero point checked, and weigh what you grind. Buy burrs when the kilograms say so.

Worth reading before you call.
- Coffee Grinder Burr Replacement — Is It Time?
Burr life is published in kilograms, not years: 400 kg for a Mazzer Super Jolly, 6,000 kg for an EK43. How to tell worn from dirty, and who should do it.
- Is It Worth Repairing an Espresso Machine?
Usually yes, if the fix costs under half a replacement and the machine has years left. The arithmetic we run by machine class, and when to buy new instead.
- How Long Does an Espresso Machine Last?
Six to eight years for an entry machine, twenty-plus for a prosumer one. The build, the water it drank and whether anyone serviced it set the number.
