There’s nothing better than waking up to the smell of fresh coffee in the morning, and there’s nothing worse than seeing a coffee maker that isn’t working right.
Luckily, most coffee maker repairings are easy and can be done with simple tools. So, before you throw away your coffee maker or go to a coffee shop, think about how they work and what to do when they don’t. You can easily check and fix the different components of the coffee maker and fix it at home by yourself. You would need some tools like screwdrivers of different sizes, or the part that needs to be replaced or changed.
Types of Coffee Makers
There are usually two types of coffee makers used. Two types of coffee makers:
- Ones that drip hot water through the grounds only once
- Ones that percolate or recycle the water through the grounds many times.
Most drip coffee makers have a control panel with switches and timers that heat water and pump it up so that it can drip through the coffee basket. The hot coffee that comes out of this goes into a carafe. The coffee stays warm because of something under the carafe.
A small amount of water is heated in the bottom of a percolator coffee maker to make steam. The steam pushes hot water up a tube in the middle of the percolator. At the top, waterfalls into the coffee basket and soaks up all the great coffee flavor from the grounds.
The hot coffee then drips through holes in the bottom of the basket and into the main part of the machine to be reused. The thermostat turns off the percolating system when the coffee has been brewed long enough. A heating element keeps the coffee at the temperature you’ve chosen.

How to Fix an On/Off Switch of Coffee Machine
Fixing the on/off switch, thermostat, heating element, and warming element are common to fixing a coffee maker.
The switch on a coffee maker is a simple device that controls the flow of electricity to the heater and pump. This key controller is easy to test and change, which is good. The steps are as follows:
Step 1: Make sure you unplug the coffee maker.
Step 2: Take off the base or shell to get to the switch’s back.
Step 3: Connect the test probes to the terminals and turn on the switch. The switch positions show that the circuit should be closed and show continuity.
You can test other controllers, like timers, with the same continuity test. They all work like switches, letting electricity through in some positions and not in others.
How to change a Thermostat for a drip coffee maker?
There is a thermostat in the coffee maker that controls the electricity. It runs the heating element in a drip coffee maker. If it doesn’t work right, it can cause trouble. To check a drip coffee maker’s thermostat:
Step 1: Unplug the unit, empty the water reservoir, flip it over, and take off the base. (You may need special head screwdrivers, which you can get at larger hardware stores.)
Step 2: Put a probe at each end of the thermostat and use a continuity tester or multitester to check it.
Step 3: If the thermostat is broken, take it out and put in a new one with the same type.
Step 4: Also, check to see if the fuse is still working, and if it isn’t, replace it.
How to Change the thermostat on a percolator coffee maker?
A percolator’s thermostat does the same as a drip system’s thermostat, but it looks different. To check a percolator’s thermostat, do one of the following:
Step 1: Unplug the coffee maker and make sure the coffee and filter are out before turning it over.
Step 2: Remove the base to get to the heating element and thermostat.
Step 3: Check to see if the thermostat works.
Step 4: Change the thermostat if it has an open circuit. If you need to unscrew or desolder the thermostat to replace it, you might want to take it to an appliance repair shop or buy a new coffee maker.
How to check or change Heating Elements in a Coffee Maker?
The heating element is an important part of a coffee maker. No one wants coffee that is cold. Either a drip coffee maker or a percolator coffee maker has a heating element that can be reached through the bottom of the machine. To check a heating element or to change it follow the following steps:
Step 1: Make sure the appliance is empty of all liquids and grounds before flipping it over to remove the base.
Step 2: Once you get to the heating element, you can test it like any other conductor with a continuity tester or a multitester. Remove the unit from the circuit, then put a probe at each terminal and make sure the element can be turned on.
Step 3: If there is no electricity, replace the Unit or group of heating elements. Mark the places of all the wires and parts you take off with masking tape, so it will be easy to put them back together.
How to check or change the Warming Elements of a Coffee Maker?
Once the coffee is brewed, the base of the coffee maker has a heating element that keeps the coffee warm. Some coffee makers have a warming element that stays on all day, so it may be the first part to break. Also, water or coffee may spill and leak into the heating element, which can cause it to short out. Here’s how to test a warming element and change it:
Step 1: Take off the bottom of the coffee maker.
Step 2: Find the heating element.
