How Do You Fix a Leaking Coffee Maker?

Introduction

A dripping coffee maker can cause a potential issue if used in homes or offices. It can create an unclean and filthy condition if the leak is not taken care of. There are many ways to fix a dripping coffee maker. This article provides an in-depth review of coffee dispensers and how a leaked coffee maker can be fixed with various methods.

Why Does A Coffee Maker Leak?

Leaks in a coffee maker can be caused by loose parts, improper installation, or even lack of use. Following are some of the common causes explained.

Incomplete Closure Of Brew Basket 

Closing the brew basket properly is essential to prevent overflows. Coffee makers are extremely hot during the brewing process. If you move your carafe without closing the brew basket, it could lead to a faulty coffee maker. To ensure that your coffee maker is closed properly, check the width of your carafe before putting it on the coffee maker. 

If the carafe is wider than four inches, close it with an additional rubber piece explicitly designed for closing baskets.

High Amounts Of Coffee Beans

If you add excessive amounts of coffee beans to the coffee dispenser, it will overflow around the filter. Also, if the opening to the cup is too small, the coffee pot may overflow.

Overfilling The Coffee Maker

Overfilling your coffee maker can lead to leaks in either brewing or carafe. If you run a brew cycle and do not fill your coffee maker to the proper level, it will overflow. Filling the carafe too much can also cause a drain around the spout or lid.

Adding More Than 16 Scoops of Pre-Ground Coffee

Remember, coffee makers, are designed to be used with 16 scoops of pre-ground coffee. This is the maximum amount of grounds to be added to the coffee maker. If extra grounds are added, it can overflow in the pot or make the carafe flow during a brew cycle. 

Open The Brew Chamber Immediately

If the brewing chamber is not opened after the brewing stops, the coffee dispenser will spill out the mixture from the filter area.

Uncleaned the Coffee Maker

Coffee makers are very simple machines. If they are not properly cleaned, they will start unnecessary spills around the carafe, basket, and brewing chamber. If not cleaned for longer, the residue can build up and cause the same problem in the coffee maker.

Removing Carafe for More Than 20 Seconds

The coffee maker is designed to keep water in the carafe at all times. Removing the carafe for 
a long period of time would allow air into the system which can cause a spill out. 

Since now we have known several reasons for leaking, let us now find some solutions to fix this problem. 

Solutions For Fixing The Coffee Maker

Clean Your Coffee Maker with Vinegar Solution

When the coffee maker starts to flow from the plastic or rubber parts, one of the most effective and easiest ways is to clean them with vinegar solution. Here is how you can do it.

Firstly, put a small amount of vinegar in the carafe before brewing and let it sit for 5 to 10 minutes. For better results, you can also add a little salt with vinegar before brewing as well. Use cool water if possible.

Fix Loose or Damaged Hose on the Bottom

Check and tighten the hose that connects the inlet valve to the bottom of the coffee maker. Make sure the plastic hose connection is not corroded or damaged. Carefully prick inside each lid seal with needle-nose pliers in case any hairline cracks are not visible. Carefully work out this process to not damage any parts inside the coffee maker lid. 

Clean or Fix The Broken Pump Valve

The pump valve is the part of the thermostat that protects the coffee maker from overheating while brewing. If this part is damaged or broken, it can cause a whole series of problems in the coffee maker. Moreover, if the pump valve is rusted or damaged, carefully remove it from the coffee maker. Clean or replace with a new one if possible.

Replace Damaged Lid and Fractured Glass

If you have broken glass or lids on your coffee maker, you should replace them with brand new ones. If the top is cracked or damaged and does not allow your carafe to seal properly, it can also cause a problem in your coffee machine.

Replace the Broken Filter Basket

If you use a plastic basket to filter the coffee grounds and the cover starts to drip, it is better to replace the plastic basket than to rebuild it. 

Adjust and Fix the Carafe

Ensure that the carafe is not cracked or chipped and all the seals are intact. Also, make sure that the lid is fixed properly and it is closed. Check to see if the seal is tight around the edges and the lid locks into place properly.

Other Major Problems In Coffee Maker Machines

1. No Power

If a coffee dispenser is not receiving any power, the reason can be a tripped circuit breaker, blown fuse, or a bad outlet. The circuit breaker, however, can be reset by flipping it back on. There are reset buttons on the front of the fuse box or behind it. A bad outlet may need to be replaced. Check your power cord if the coffee maker still doesn’t work.

2. Machine Stops Running

This is a common problem and it’s very easy to fix. The underlying reason is the level of water in the dispenser has reached a low level. The clogging of the filter paper can also be another reason why the coffee dispenser stops functioning.

3. Coffee Doesn’t Brew 

This may happen if your coffee grounds are too old and stale. Try using new coffee beans instead of old stale ones or grind them fresh before brewing. Also, if you are using ground coffee in your coffee maker, stir the grounds well before brewing.

4. Inconsistent Working

This may happen because there is something stuck inside your coffee maker. The most common problem is a stuck plunger. This occurs when the plastic assembly from where the grounds move is gummed up. This affects the working of the plunger.

5. Clogged Filter Basket

Clean the filter basket under running water before brewing again. Simply remove the entire coffee maker’s interface and use fingers to shake out any old residue that may be stuck inside.

6. Carafe Doesn’t Hold Heat

It’s important to know that glass doesn’t hold heat very well as compared to thermal carafes. So using a glass carafe will tend to cool down your coffee rather quickly. If this seems non-feasible, then replace the carafe with a thermal one. 

7. Machine Handle Popping Off

This situation occurs when the coffee maker is used frequently and the handle gets dislodged. Check if the plastic latch is still on. If it is, make sure to re-secure it by putting a small drop of glue. 

8. Milk Frothing Issues

For this issue, proper temperature settings are required which can be checked through an instruction manual. Another reason can be a clogged steamer wand which can make the frothing process harder to complete. 

9. Bad Coffee Taste

This can happen due to a lack of water during brewing or a clogged filter. Check the amount of water in the dispenser and adjust as directed. Clean the filter basket or use a paper filter to clean it and remove any residual coffee grounds.

10. No Steam Arm Pressure 

This is very simple to fix. First, you will have to check if the steam arm is properly attached and make sure that the pressure valve is properly screwed in place. Some of these machines have a built-in coffee grinder which has a compartment for storage and cleaning. Others are self-contained and have no moving parts whatsoever.

Coffee makers are very simple devices to operate but fail at times due to improper care and maintenance. The most common problem areas are water and heating systems which also cause odor and leaking problems in your coffee maker. Make sure that you solve these common problems as soon as possible before it becomes difficult to solve.

Coffee Machine Maintenance Guidelines

1. Clean the machine at least once a week, especially if you brew your coffee in the morning. Use hot water to clean the machine. This will keep the coffee maker clean and provide a delicious cup at all times. 

2. Avoid cleaning the device at night since electricity will be required to ensure its dryness. A cold appliance can contract metal parts, so the cleaning mechanism should be done while the coffee dispenser is hot. Dry it out with a towel or paper towels. 

3. If you are using a glass carafe, clean it at least once a week. Also, do not wash it directly in the dishwasher.

4. It is very important to clean and decalcify your coffee maker regularly. This will help keep the device working properly and you will get better tasting coffee every time.

5. There are two types of removable elements that make up a coffee maker. One is the filter basket and the other is the carafe. There are different techniques for cleaning and maintaining these parts. You should check your machine’s manual and follow its instructions for the specific care of individual machine components.

6. The coffee maker’s water reservoir should be filled with water before starting to brew. The water needs to be hot but not in a boiling state. If left unfilled for a long time, the heating element will get clogged and not work properly.

7. Unfortunately, many people do not know how to clean their coffee machines properly. Others think that coffee makers can automatically clean themselves. Try cleaning the appliance on a regular basis to avoid any mishappening. 

8. Never put your machine near any heat source or a window. This will increase the chance of overheating which will lead to malfunctioning of your coffee maker. Elevate it on a surface at least 2 inches high, away from dusty areas.

Q: Is a thermal carafe better than a glass one?

A: Yes, it is usually better because it is more reliable. Glass carafes do break and leak from time to time. Thermal carafes are not fragile and thus, safer from damage.

Q: How does a thermal carafe work?

A: The thermal carafe is insulated and is made of a stainless steel or glass material. As it cools down, the interior temperature decreases and releases the stored coffee. This type of carafe also has a lid that keeps the heat inside during storage and transport. A container holds about 30 ounces.
