Cuisinart CHW-16 Series Coffeemaker & Hot Water System: Common Coffee Maker Problems
1. Coffee Not Brewing
If your Cuisinart Coffee PLUS® isn’t brewing coffee, this is a common issue that can be caused by several factors. Here’s what you can do to resolve it.
Possible Causes:
- Power Supply Issue: If the machine isn’t powered on properly, it will fail to brew.
- Clogged Filter or Water Line: A blocked filter basket or water line can impede the brewing process.
- Empty Water Reservoir: If the water reservoir is empty, the machine cannot brew.
Solutions:
- Check Power: Ensure that the coffee maker is properly plugged in and turned on. If the power cord is damaged, it may need to be replaced. If the power is functional, verify that the control panel is lit up.
- Clean the Filter Basket: The filter may be clogged with old coffee grounds. Remove the filter basket and clean it thoroughly with warm, soapy water. Rinse it well to remove any soap residue. If you use a gold-tone filter, make sure it is not obstructed by old grounds.
- Refill the Water Reservoir: The water reservoir must be filled to the appropriate level. If the reservoir is empty, the unit won’t brew. Make sure the water tank lid is properly closed to prevent leaks.

2. Coffee Overflowing
Coffee overflowing is another common issue, and it can be caused by overloading the filter or improper brewing settings. This issue can also lead to spills and messes on your countertop.
Possible Causes:
- Too Much Coffee Grounds: Using more coffee grounds than the recommended amount can result in overflow.
- Clogged Filter or Water Line: A clogged filter can prevent water from flowing properly, causing the coffee to overflow.
- Wrong Coffee Grind: A grind that is too fine can clog the filter, leading to an overflow.
Solutions:
- Adjust the Amount of Coffee Grounds: Ensure that you are using the correct amount of coffee grounds. For the Cuisinart CHW-16, use one tablespoon of ground coffee per cup. Do not exceed the recommended amount (15 tablespoons).
- Check the Coffee Grind: Use a medium-fine grind for best results. A very fine grind can block the filter and cause water to overflow.
- Clean the Filter Basket: Remove any coffee grounds or old filters that may be clogging the basket. Clean the filter thoroughly to ensure proper drainage.
3. Weak Coffee
Weak coffee is a frequent issue, and it usually stems from incorrect brewing settings or improper coffee grind.
Possible Causes:
- Incorrect Coffee Grind: Using too coarse a grind will cause water to flow through the grounds too quickly, resulting in weak coffee.
- Insufficient Coffee Grounds: If you’re not using enough coffee grounds, the resulting brew will be too weak.
- Incorrect Water Temperature: The water temperature may not be high enough to brew strong coffee.
Solutions:
- Adjust Coffee Grind: Use a medium-fine grind for optimal extraction. If the grind is too coarse, the water will pass through too quickly and the coffee will be weak.
- Increase the Coffee Amount: If the coffee is still weak, increase the amount of coffee grounds slightly. The recommended ratio is 1 tablespoon per cup of coffee, but you can increase it slightly based on your personal taste.
- Ensure Proper Water Temperature: The Cuisinart CHW-16 brews coffee at the optimal temperature of around 200°F. If you are using a lower temperature setting, the coffee might not extract fully.
Hot Water System Issues
The Cuisinart CHW-16 also includes a hot water system, which can sometimes encounter issues. If you are facing problems with hot water dispensing or heating, follow these solutions.
a. No Hot Water Dispensed
If the hot water system isn’t dispensing water, there are a few potential issues to check.
Possible Causes:
- Empty Hot Water Reservoir: If the hot water reservoir is empty, no water can be dispensed.
- Clogged Hot Water Dispensing System: Mineral buildup from hard water can clog the dispensing system, leading to no water being dispensed.
Solutions:
- Check Hot Water Reservoir: Make sure the hot water reservoir is filled to the maximum fill line. Do not overfill the tank, as this can cause spillage.
- Clean the Dispensing System: If you have been using the hot water system for a while, it may have accumulated calcium deposits. Perform a cleaning cycle using a mixture of vinegar and water to flush out the system.
b. Hot Water Not Heating
Hot water not heating properly can be frustrating, especially when you’re depending on it for tea or instant coffee.
Possible Causes:
- Faulty Heating Element: The heating element may be malfunctioning, which would prevent the water from heating.
- Water Not Reaching Optimal Temperature: The hot water system may not be reaching the required temperature for proper heating.
Solutions:
- Check the Heating Function: If the water is not heating, ensure the unit is turned on and the “Hot Water On” indicator is illuminated. If it’s not, press the button again.
- Reset the Machine: Unplug the coffee maker, wait for about 10 minutes, and then plug it back in. This may reset the heating function.
- Contact Cuisinart Support: If the water is still not heating, there may be an internal issue with the heating element. Contact Cuisinart customer service for further assistance.
Power and Display Issues
i. Power Failure
A power failure can affect the performance of both the coffee maker and hot water system.
Possible Causes:
- Electrical Issue: If the machine is not getting power, the problem could lie in the electrical connection or power source.
- Circuit Breaker Tripped: The circuit breaker in your home may have been tripped, cutting power to the unit.
Solutions:
- Test Power Source: Plug another appliance into the same outlet to ensure there is power. If the second appliance works, the problem may be with the coffee maker.
- Check Circuit Breaker: If the coffee maker is still unresponsive, check your circuit breaker to see if it has been tripped. Reset the breaker if necessary.
ii. Unresponsive Display
If the control panel or display is unresponsive, there may be an issue with the internal electronics.
Possible Causes:
- Electrical Disconnection: A loose connection inside the unit may cause the display to freeze.
- Software Issue: Sometimes the software or firmware of the coffee maker may cause it to stop responding.
Solutions:
- Reset the Unit: Unplug the unit from the power source and leave it unplugged for about 10 minutes. After that, plug it back in and check if the display responds.
- Contact Support: If the issue persists, the control board may need to be replaced. Contact Cuisinart support for assistance.
Maintenance and Cleaning Solutions
Proper maintenance is essential to keep your Cuisinart CHW-16 functioning optimally. Regular cleaning and decalcification can prevent many common issues.
Decalcification Problems
Over time, mineral buildup can cause the unit to operate inefficiently, especially with hard water.
Solutions:
- Decalcify Regularly: If the “Clean” indicator light starts flashing, it’s time to clean the coffee maker. Use a mixture of 1/3 white vinegar and 2/3 water to run a cleaning cycle. This will remove calcium buildup from the system.
- Clean the Hot Water System: Run a decalcification cycle using vinegar for the hot water system as well, especially if you use it frequently.
Regular Cleaning Procedures
For optimal performance, follow these cleaning steps regularly:
- Filter Basket and Coffee Grounds: After each use, remove any coffee grounds and clean the filter basket. Wash it with warm soapy water or place it in the dishwasher.
- Carafe and Lid: Wash the carafe and lid with mild detergent and warm water. You can also place them in the top rack of the dishwasher.
- Hot Water Reservoir: Empty the hot water reservoir after each use, especially if the system hasn’t been used for a while.
FAQs
How often should I replace the water filter?
It’s recommended to replace the water filter every 60 days or after 60 uses, especially if you have hard water.
Why is my coffee not hot enough?
Check the carafe temperature setting. The heating plate can be adjusted to Low, Medium, or High. Also, ensure that the water temperature is set correctly.
Can I use other filters besides the Cuisinart brand?
Using non-Cuisinart filters could cause overflow or improper brewing. Always use the recommended filters to prevent issues.
