How to fix a broken coffee maker

Whether you have an inexpensive coffee maker or an expensive one, coffee makers are easy to fix. They have a fundamentally simple design consisting of a few essential components.

A simple drip coffee maker has several electronic components that heat the water and deliver it to the ground coffee. It also has a mechanism to keep the jug containing the coffee warm.

Repairing a broken coffee maker involves isolating the problematic component, including the power switch, fuse, heating element, thermostat, and heating element.

Step 1. Prepare your coffee maker

Always start the repair process by disconnecting the device from the power source. Empty the water tank. You don’t want water dripping onto the electrical components of your unit. Also, remove the coffee basket and filter.

Consult your owner’s manual for instructions on how to remove the casing or stand from the machine. You may need a special screwdriver for this step, depending on your drive.

Step 2. Check the power switch

Set your multimeter to ohms and place the test leads together or close together. Check the readings on your tester as you will be using this data as a reference.

Turn on the power switch of your coffee maker and place the test probes in the connections. The reading should be similar to your reference value. If not, you may have a broken on/off switch. Coffee machine power switches can cost you anywhere from a dollar to five dollars.

Step 3. Check the fuse

Fuses can fail much faster than other electrical components. Using the same method described above, you can also check the continuity of the circuit.

If the reading is not close to the reference value, you may have a blown coffee maker fuse. You can buy a fuse for around three cents to three dollars.

Step 4. Check the thermostat

Locate the coffee maker’s thermostat and check its electrical connection. A broken thermostat requires replacement, which can cost anywhere from $3 to $10, depending on the brand.

You must purchase a thermostat with the same voltage and amperage as the faulty thermostat. For example, if the faulty unit is rated at 120 volts and 16 amps, you should get a 120 volt 16 amp coffee maker thermostat.

Step 5. Check the heating element

Perform the same test on the heating element of the coffee machine. If it is defective, mark the various components of the heating element and the cables with masking tape. Remove the defective heating element and replace it with a new one. Reconnect the various cables and components.

Step 6. Check the heating element

Your coffee machine has a hot plate that accommodates a coffee pot. You can test your heating element using the method we outlined above, and replace the component if it’s faulty.

Step 7. Reassemble your coffee maker

After repairing the coffee maker, you can reassemble it by placing the base or the casing. It would be best to test all components before reassembling.

How to fix a broken espresso machine

A manual espresso maker is much easier to repair because there are no complicated mechanical parts. You create pressure by pressing the lever.

On the other hand, automatic espresso machines have complicated components and circuitry that can be a challenge for even a seasoned DIYer. Still, you can make some quick repairs to a broken espresso machine.

Step 1. Check that water is flowing through the machine

Hot air from the boiler can pressurize the machine’s pump to create a vapor lock.

To repair, turn off the espresso machine for about 30 minutes. Refill the machine with fresh, cold, filtered water. Turn on the device, activate the steam pipe and let the water run for two minutes.

Activate the cook mode and backwash the unit for two minutes while keeping the steam wand in the ON position. Turn off the cooking mode and let the water run through the steam wand for another two minutes. Turn off your machine.

Step 2. Check if steam is coming out of the steam line

Check that the steam indicator shows at least 1 bar. If so, your device may have a different problem. If the pressure gauge reads ‘0’, you may want to reset it and see if that fixes the problem.

Clean the top of the steam pipe with a suitable tool to remove the blockage. It should give you enough steam for your milk-based coffee drinks.

Step 3. Make sure your espresso has foam

The rich crema differentiates a fantastic espresso from a mediocre caffeinated drink. If you don’t see this sweet coating on your shot of espresso, there must be a problem.

Understand that the quality of the foam is a function of the coffee beans. Coffee grounds that are too thick or burnt coffee beans do not create a velvety foam. Water temperature can also affect custard production, with an ideal temperature of 195 degrees Fahrenheit.

Also check the cooking pressure on the appliance. Ideally, you want a shot of espresso in 20 to 30 seconds. A faster or longer withdrawal can result in a poor quality cream. It also tells you that the machine has a problem with brew pressure.

If performing the steam cap procedure does not resolve the issue, you may need to take the espresso machine to a service center.


Most coffee and espresso machines have a simple design. Only complex superautomatics require a more professional repair. If not, following the simple steps to fix a broken coffee maker and espresso machine should save you the hassle of buying a new appliance or hiring a professional to do it for you.
