Keurig Mini B-31 Troubleshooting

The handle of the machine is broken, cracked or will not push down properly.

If the handle of the machine is broken or cracked, you will need to purchase a replacement online. Use this guide to help you replace the handle. A cracked handle may cause it to not push down properly.

Water leaks out of the machine instead of flowing through.

If water is leaking at the base of the machine, the K-cup holder could be cracked. This would allow water to seep through. First check near the K-cup holder of the machine to locate any possible cracks. Once found, the K-cup holder must be replaced using this guide.

If water is leaking near the K-cup holder, check to see if the K-cup holder is damaged. If the K-cup holder is not damaged, the hose may be clogged. You will have to open up the top of the Keurig to check for this by following this hose cleaning guide.

The water is not flowing through the K-cup correctly.

If the water overflows around the K-cup holder instead of dispensing, then your needles may not be penetrating the K-cup or the K-cup holder may be clogged. If the K-cup holder is not clogged, check this guide for replacing the top needle.

If the water poured into the reservoir does not drain, it will not reach the K-cup. The drain on the Keurig may be clogged. To check if the drain is clogged and possibly unclog, use this guide to help you unclog your drain.

The coffee is dispensing, but at a slower rate than when the machine was new.

If water is dispensing abnormally slow, check to see if the top needle is dull. If it is dull, the needle will need to be sharpened. If the needle is sharp, then the needle may need to be cleaned.

Cleaning or sharpening the needle can be done by following this guide needle replacement guide.

If coffee is dispensing slowly, the water hose may be partially clogged. This can occur if the water in the reservoir is hard water with a high mineral content. Poor water quality can result in buildup of minerals in the dispensing tube. Unclog it using the hose cleaning repair guide.

The machine is not producing the full amount of coffee.

If there is build up or the K-cup has not been removed, then the water will not flow through the machine as smoothly. Remove the K-cup promptly after brewing. Proceed to clean/wipe down with a soft, damp cloth. The K-cup holder can to be washed on the top shelf of the dishwasher on a low temperature cycle.

If either the entrance or exit needles are clogged, then not all of the water will flow through. Use a straightened paper clip to enter into both the exit and entrance needles to free both from any and all coffee grounds.

The machine has stopped heating up to the temperature it is supposed to be.

If cold water is being used, the water being pumped through the brewer may not reach the temperature it is supposed to be. Warm the cup in advance by filling it with hot water and let sit for a minute or two before pouring out. Proceed to fill the cup with the desired amount of creamers before brewing coffee. Be sure to use room temperature water when filling the machine.

If the water heater is malfunctioning, then the water will not heat up to the proper temperature. Heating occurs when water is being pumped through the brewer, resulting in hot coffee. Take the machine apart and replace the water heater unit.

The coffee has a bad taste after being brewed.

If tap water is being used, a bad taste can occur in the coffee as a result of minerals and residue in the tap water. Boil the tap water before brewing the coffee. If there is still an odd taste, use a filter for the tap water before brewing the coffee.

If there is a scaling or mineral buildup, the water will collect it when flowing through. Mix vinegar and water and let soak in the machine. Then flush the mixture with filtered or boiled water. If the taste still occurs, purchase descaling solution and clean the machine thoroughly by disassembling and cleaning each part.
