Coffee System Repair


There’s nothing more pleasant in the morning than the smell and taste of fresh coffee.

How Coffee Maker Machines Work

There are two types of coffee makers in common use: the first drip hot water once through the coffee grounds, the other recycle the water through the grounds many times.

Usually coffee maker machines are activated by switches and timers in the control panel, heating water and pumping it up to drop through the coffee basket. The resulting hot coffee falls into a carafe and the element under it  keeps the coffee warm.

Percolator coffee maker machines heat a small amount of water in the base of the unit, which pushes the hot water up a tube in the center of the percolator. At the top, water falls into the coffee basket, soaking up coffee flavor from the grounds. The hot coffee then drips through holes in the basket base and into the main compartment to be recycled, then it continues to maintain the coffee at the selected temperature.

How to Repair a Coffee Maker

Common repairs to coffee maker machines include

  • servicing the on/off switch
  • thermostat
  • heating element
  • warming element

Servicing an On/Off Switch:  Switch is a simple device that controls the heating unit and pump. It is easy to test and to replace.

  • First of all make sure that the coffee maker machine is unplugged.
  • Then remove the base, in order you can access the back of the switch.
  • And at last place test probes across the terminals and then activate the switch.

Servicing a Drip Coffee Maker’s Thermostat: A thermostat in drip coffee maker machine controls electricity, which operates the heating element.

  • First of all unplug the appliance, empty excess water from the reservoir, turn the device over, and remove the base.
  • Then you should use a continuity tester or multicenter to check the thermostat, placing a probe at each end.


If it doesn’t work, remove and replace the thermostat with one of the same rating.

Servicing a Percolator Coffee Maker’s Thermostat: The thermostat in a percolator coffee maker machine aims the same function, but looks different from that of a drip system.

  • First unplug the coffee maker machine, make sure the coffee and filter are removed before turning it over, then remove the base to expose the heating element and thermostat.
  • Test the thermostat’s continuity.
  • If the thermostat doesn’t work replace it.


Servicing Heating Elements: A coffee maker’s heating element is an important component, which is accessed through the base of the appliance.

  • First of all make sure all liquids and grounds are emptied from the device before turning it over to remove the base.
  • Then use a continuity tester or a multitester as you. Then disconnect the unit from the circuit and place a probe at each terminal and verify that the element can

conduct electricity.

  • At last if no electricity is being conducted, replace the heating element.

Servicing Warming Elements: The warming element on coffee maker machine remains on all day long, so it may be the first component to fail. Often water or brewed coffee may spill and leak into the warming element, shorting it out.

  • First of all remove the coffee maker machines base, identify the warming element, and disconnect it from the terminals.
  • Then check for continuity using a continuity tester or multitester.
  • And replace the warming element, if it doesn’t work.
