cuisinart coffee maker not turning on

Is your Cuisinart Coffee Maker not turning on? Depending on the signs it shows, the cause could be in different components.

You will have to investigate it thoroughly according to the guide below.

A Cuisinart coffee maker that refuses to turn on might have a clog in its hoses or ball valve, but it could also suffer from a defective power cord. Moreover, the cause may rest on the buttons/knobs and their internal panel or the heating element.

We are sure you are eager to find the solution that fits the issue behind your coffee maker’s malfunction.

Below we will discuss the main causes and how you can proceed.

Cuisinart Coffee Maker Not Turning On – Reasons

reason why the coffee maker not turning on

Cuisinart coffee makers are very popular due to their quality and features. Because of that, the issues are well-documented too.

If your Cuisinart coffee maker won’t turn on, you must check below to learn about the most common causes:

Defective Power Cord

Sometimes our appliances and devices don’t turn on anymore, but all that’s happened is the power cord stopped working.

Damaged Heating Element

The heating element is responsible only for heating the water. Still, it could cause the whole coffee maker to stop functioning.

Too Many clogs

Coffee makers will eventually clog due to coffee dust left behind and minerals in the water. 

Malfunctioning Buttons

The buttons are also a component of your coffee maker that can occasionally fail. 

How To Fix The Cuisinart Coffee Maker

You already know why your Cuisinart Coffee Maker does not turn on. Next, it is time to make your coffee maker turn again.

You might want to get prepared with a few tools or cleaning items.

1. Test The Power Cord

Before wondering whether the coffee maker is damaged beyond repair, you should check the power cord.

First, do this:

  1. Unplug the power cord;
  2. Test it in another outlet;
  3. Check for signs of damage on its length;
  4. Look closely for parts where the rubber could be thinner than the rest.
  5. Grab a multimeter and set it to continuity;
  6. Touch its probes to the cord’s end.

If the results are fine, you don’t need to install a new power cord. 

Check And Replace

Before replacing the power cord right away, you can also do this:

  1. Disassemble the coffee maker to find the cord’s wiring;
  2. Check for internal damages, burns, or loose wires;
  3. Fix anything possible.

If there is nothing to fix and the cord is no longer functional, do this:

  1. Carefully detach the damaged cord from the internal wiring;
  2. Connect a new power cord;
  3. Reassemble the coffee maker.
Note: Remember to buy a power cord with the same electrical specs as your coffee maker.

2. Unclog The Coffee Maker

Since the coffee maker is not turning on, you will not do the regular unclogging cycle.

Instead, proceed through a deep unclogging method. Here is what you will do:

unclog the coffee maker
  1. Remove the bottom plane;
  2. Access the water lines;
  3. Detach the hoses;
  4. Use a small brush, soap, and water to clean;

Reassemble the hoses once they are clean, with no soap residue in them.

Check The Ball Valve

Once you have removed the bottom plate, you can access the ball valve. That valve determines the water flow direction.

You must do this to test it:

  1. Detach it from its place;
  2. Shake the valve;
  3. Is the ball free? If yes, that’s a good sign;
  4. Next, try blowing on it;
  5. Air should go only in one direction, but if you can’t blow, that’s a bad sign.

There could be too much buildup in the ball valve too. Clean it the same way you did with the hoses and reassemble it.

Note: It is a good idea to remove the brew basket and unclog it, just in case. When you manage to turn the coffee maker on again, run an unclogging cycle with vinegar. That will eliminate all mineral buildup.

3. Check The Knobs/Buttons

check the knobs and buttons

Depending on the Cuisinart coffee maker’s model, it has many knobs and buttons. Unfortunately, those, including the “Power” button, can be damaged over time.

So first, you must check the following:

  • Are there cracks or signs of burning on the buttons/knobs?
  • Is any knob a bit loose? 
  • Is any button lodged inward?
  • Does it look like there is too much dirt and dust on the control panel? 

If there is dirt and dust, it is a good idea to use rubbing alcohol to clean the surface.

As for the lodged buttons, you can use a toothpick to try and carefully dislodge them.

Fix Or Replace A Knob

You must disassemble the control panel if there is a broken or damaged knob.

Here is how:

  1. Find the screws and remove them;
  2. Carefully lift the panel off;
  3. Find the place where the defective knob is;
  4. Check if its internal components are damaged.

Depending on how it looks, you could simply put the knob back in place by adjusting its components. Otherwise, remove it and buy a new knob to put in place.

3. Replace The Heating Element

A common cause of malfunction in Cuisinart coffee makers is the heating element. Even though it lasts a long time, it can blow out or have its joints severed.

That could be the case if you drink a lot of coffee daily. Here is how you can approach the hypothesis:

replace machine heating element
  1. Unscrew the bottom’s screws;
  2. Take the bottom apart;
  3. Check the heating element’s status.

The heating element could be severed on the joints, which is fixable. Also, it could be whole, without any visible issues.

In that case, you will grab a multimeter and test it for continuity. Is it defective? Then replace it. 

Fix The Joints

Are the joints loose or severed? Those can be fixed depending on their state. You will need to solder them back.

The process is very simple:

  1. Use the solder to make a bit of melted iron;
  2. Drop a bit into the joints;
  3. Ensure they stay in place;
  4. Test with the multimeter to see if electricity can flow.

Replace The Element

If the heating element looks like it can’t operate anymore, you must buy a replacement.

Once you have the replacement in your hands, do this:

  1. Detach any wires from the defective part;
  2. Remove screws and bolts;
  3. Dispose of the damaged component;
  4. Put the new heating element in place;
  5. Attach the wires;
  6. Tighten the screws.

Then, test your coffee maker. It should work right now.

Note: Replacing the heating element might be the best idea instead of fixing the old one. A new heating element is guaranteed to last longer.

5. Assess The Internal Wiring

If you are experienced with electronic devices, you might want to check the internal wiring of your coffee maker.

If you are not, then you better call a technician or Cuisinart support.

Here is how you can check if it is necessary to fix internal wiring:

  1. Locate the place where the LCD or button component is fastened;
  2. Detach it by unscrewing;
  3. Clean dust away if there is any;
  4. Check for loose or burned wires;
  5. Fix anything that looks like you can fix it;
  6. Check if any button’s mechanism is damaged or lodged.

Be careful not to damage any wires or electronic circuits. Then reassemble the panel and test the coffee maker again.

Note: If you can't find what's wrong with your coffee maker and the internal wiring doesn't look bad, you should now call brand support or a technician.
