Kureg b 50 water wont pump - Keurig B50 Coffee Maker

It's water mineral residue. You should have used vinegar instead of bleach, though. If the thing still pumps a full cup then forget what Kureg has to say.

If your pump had something in it, it wouldn't have had to clog it, but rather just stopped the internal spinning. My coworker removed a dollar bill from his water pump, and it fixed the problem he was having (same as you've described) and the water pump worked well after it was re-installed.
Worst case scenario, you reinstall it and it doesn't drain and you spend 40 or 50 bucks online for the part. I would reinstall and see if it works. I'd bet on it.

CHECK COOLANT LEVEL MOST NEWER VECHICLE DONT HAVE RADIATOR CAP YOU HAVE TO POUR COOLANT IN THE COOLANT OVERFLOW JUG THE COOLANT WILL GO TO RADIATOR. IF THE COOLANT OVERFLOW JUG EMPTY ADD COOLANT UNTIL COOLANT LEVEL STOP DROPPING AT STAY AT FULL COLD MARK.IF COOLANT OKAY,NEED TO REPLACE THERMOSTAT AND COOLANT OVERFLOW JUG PRESSURE CAP. IF ALL BEEN DONE. MOST OF THE TIME WHEN CAR OVERHEATING WHILE MOVING. RADIATOR CORES STOPPED UP OR RADIATOR GRILLE DIRTY OR RESRICTED.ENGINE BLOCK COOLANT PASSAGES CLOGGED AND HEATER CORE CLOGGED.CHECK WATER PUMP SEE IF WATER PUMP WEEP HOLE LEAKING IF SO REPLACE WATER PUMP.IF ENGINE OVERHEATING AT A LONG TRAFFIC LINE ENGINE COOLING FANS NOT RUNNING EITHER COOLING FANS FUSE AND RELAYS BAD.OR ENGINE COOLANT TEMPERATURE BAD. THE ENGINE COOLANT TEMPERATURE SENSOR TURNS ON COOLING FANS AT A CERTAIN TEMPERATURE IF SENSOR BAD FANS WONT TURN ON. MAKE SURE YOU HAVE 50 /50 MIXTURE OF COOLANT AND WATER IN COOLING SYSTEM.

SOUND LIKE THERMOSTAT STICKING CLOSE.REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP.ADD 50 /50 MIXTURE ANTIFREEZE AND WATER TO THE COOLANT SYSTEM.CHECK TO MAKE SURE WATER PUMP NOT LEAKING IF SO WATER PUMP NEED REPLACING. ALSO DO A QUICK CHECK.CHECK ENGINE OIL DIP STICK. IF LOOKS LIKE MILK SHAKE HEAD GASKET LEAKING.

IT probably is the circutboard inside the Kureg I suggest you go buy a new one or try and google how to open it and fix it

Is the little pipe that connects to the pressure switch clear?

I suggest you remove it and blow through it to make sure it is clear. If the pressure is getting to the switch, it has to shut off ... your switch should be set around 30/50 (on at 30 - off at 50)

You may need to run a pot of white vinegar and water (50/50) through several times to flush out the line and heater. Make sure that the plate under the pot is getting very hot or it won't pump water from the reservoir. Hope this helps!

the fuel system is seperate from heating system.check water pump the impeller could have deteriated i have seen this in another cavalier,once i removed water pump the blades that move the water were full of holes.but first make sure ther is good flow to the heater core.also hope you used a 50/50 mix of antifreeze because solid antifreeze wont heat up.

A lot of It depends on the condition of your coolant. or the percentage of coolant vs water.
50/50 is best. Too much coolant wont cool as good. Too much water and the lubrication and protection is lost. Then the waterpump goes out from lack of lubrication.
The water pump can also go out from the driving belt being too tight. Whether it is driven from the timing belt or a serpentine belt or a V belt.

have u checked the coolant level?if its low you wont get much heat.
