Mueller Coffee Maker Troubleshooting. I have repaired a couple coffee makers by forcefully spraying water into the fill area.(unplug first of course). Squeeze this little sucker here and force it to blow out whatever kind of snot is.

Be sure that your auto shut off switch is also in the right position. When the machine does not run after you turn it on, disassemble the grinder and. Run the keurig as you normally would make coffee.
