Machine Not Powering On or Not Heating
When you plug in your Keurig B155 and nothing happens, it’s frustrating.
Check the power cord for damage or kinks, ensuring a secure connection to both the machine and the wall outlet. Verify the outlet is working by plugging in another device.
If the issue persists, try resetting the machine by unplugging it, waiting 30 seconds, and plugging it back in.
If your Keurig B155 still won’t power on, it may indicate a faulty power supply or electrical component failure. In this case, contact Keurig’s customer support for further assistance or potential repair options.
Water Dispensing Issues
When you’re experiencing water dispensing issues with your Keurig B155, you’ll want to start by checking the water reservoir to verify it’s properly filled and seated.
Next, inspect the dispensing line for any blockages or kinks that could be restricting water flow.
You should also clean the water reservoir regularly to prevent mineral buildup and bacterial growth, which can also affect water dispensing performance.
Check Water Reservoir
The water reservoir is a critical component of your Keurig B155, as it supplies water to the brewing process.
If you’re experiencing water dispensing issues, guarantee the reservoir is filled to the recommended level. Check the water level indicator to confirm it’s not empty.
Also, inspect the reservoir for any blockages or mineral buildup that might restrict water flow. Clean or descale the reservoir if necessary.
Make certain it’s properly aligned and seated on the brewer to prevent any leaks or issues.
Inspect Dispensing Line
If the water reservoir is filled and clean, but you’re still experiencing water dispensing issues, your next step is to inspect the dispensing line. Check for kinks, blockages, or damage that might restrict water flow. A clogged or damaged dispensing line can prevent your Keurig from dispensing water properly.
| Section | Issue | Solution |
|---|---|---|
| Dispensing Line | Kinked or bent | Straighten or replace |
| Dispensing Line | Clogged with debris | Clean or replace |
| Dispensing Line | Damaged or cracked | Replace |
| Dispensing Line | Loose connection | Tighten connection |
| Dispensing Line | Blocked by scale buildup | Descale the machine |
Clean Water Reservoir
Scale buildup, mineral deposits, and old or stagnant water can clog your Keurig’s water reservoir, causing water dispensing issues.
You’ll need to clean the water reservoir to resolve this problem. Remove the reservoir from the machine and wash it with warm soapy water. Rinse thoroughly and dry with a clean towel.
Descale the reservoir every 3-6 months to prevent mineral buildup. You can use a Keurig-approved descaling solution or a mixture of equal parts water and white vinegar. Fill the reservoir with the solution, let it sit for 30 minutes, and then rinse thoroughly.
Leaks and Poor Coffee Quality
While brewing, your Keurig B155 suddenly sprays coffee grounds everywhere, or you’re left with a lukewarm, under-extracted cup – these issues with leaks and poor coffee quality can be frustrating and wasteful.
Leaks can occur due to clogged or damaged brew needles, worn-out O-rings, or misaligned K-cup holders. Check the brew head for blockages and clean it regularly. Inspect the O-rings for signs of wear and replace them if necessary.
Guarantee the K-cup holder is properly aligned to prevent coffee grounds from spilling out. By addressing these potential causes, you can troubleshoot and resolve leaks and poor coffee quality issues with your Keurig B155.
Maintenance and Replacement
Regular maintenance is essential to extend the lifespan of your Keurig B155 and guarantee it continues to brew great-tasting coffee.
You should clean the machine regularly, emptying the drip tray daily and wiping it down with a damp cloth.
Clean the water reservoir weekly with warm, soapy water and rinse thoroughly.
Descaling every three months and replacing the water filter every two months are also must-dos.
Don’t forget to check the brewer’s pump periodically and replace it if necessary.
General Tips and Troubleshooting
When troubleshooting your Keurig B155, it’s essential to follow a methodical approach to identify and resolve the issue efficiently.
You’ll want to start by checking the machine’s power status, as a lack of power can be a common and easily resolvable problem.
Machine Not Powering
If your Keurig B155 won’t turn on, don’t assume it’s dead just yet. First, inspect the power cord for any signs of damage, such as cuts, frays, or kinks. If it’s damaged, replace it with a new one from the manufacturer.
| Potential Issue | Solution |
|---|---|
| Damaged power cord | Replace with a new one from the manufacturer |
