Maintenance coffee machines usually include maintenance start switches, thermostats, heating elements and insulation elements.

Maintenance start switch: The coffee maker switch is a simple device that controls the heating unit and coffee pump switch. Fortunately, this critical controller is easy to detect and replace. The specific steps are as follows:

Step 1: Make sure the coffee maker is unplugged.

Step 2 Remove the base or housing to access the back of the switch.

Step 3: Connect the detection probe to the two terminals and turn on the switch. At this time, the circuit should be closed, and the switch position should indicate the path.

This on-off detection also applies to other controllers, such as timers. All controllers work on the same principle as switches, conducting current at some settings and interrupting current at others.

Maintenance of a drip coffee maker thermostat: In a drip coffee maker, the thermostat controls the current through the heating element. If the thermostat does not work properly, it will cause many problems. Here's how to detect the thermostat in a drip coffee maker:

Step 1: Unplug the coffee maker, empty the reservoir of water, turn the coffee maker upside down, and remove the base (you may need to use a special head screwdriver, which is generally available at larger hardware stores).

Step 2: Connect the probes of the on-off detector or multimeter to both ends of the thermostat, and then test the thermostat.

Step 3: If the thermostat is faulty, remove the thermostat and replace it with a model with the same rating.

Step 4: In addition, check the continuity of the fuse. If the circuit is open, replace the fuse.

Maintenance of heating elements: In coffee machines, heating elements are a critical component. No one wants cold coffee. Whether it's a drip coffee maker or a percolator coffee maker, to access the heating element, you need to remove the base of the appliance. Here are some ways to test and replace heating elements:

Step 1: Make sure to empty the appliance of all liquids and coffee grounds before turning it upside down to remove the base.

Step 2: Once the heating element is exposed, it can be tested with an on-off detector or multimeter just like any conductor. Disconnect the device from the circuit and connect probes to both ends of the component to verify that the component conducts electricity.

Step 3: Replace heating element or entire assembly if it does not conduct electricity. Mark the location of all loose wires and components with masking tape so they can be reconnected.

Maintenance of insulation elements: After brewing coffee, the insulation element at the bottom of the coffee machine will keep it warm. In some coffee makers, the insulation element is on all day, so this component is prone to failure first. In addition, water or brewed coffee may splash or leak onto the insulating element, causing it to short circuit. The following is a description of how to test and replace insulation elements:

Step 1: Remove the base of the coffee maker, locate the insulation element, and disconnect it from the terminals.

Step 2: Use an on-off detector or multimeter to check the continuity of the component.

Step 3: Replace insulation elements as needed.
