Reference: Whirlpool Refrigerator, Model ET1FTTXK B02; mfg 2003
Perhaps this will help somebody. About a year ago, our relatively new
Whirlpool refrigerator has a filtered water system, and both the ice maker
and the dispenser suddenly stopped working. I could hear the electric water
solenoid operate, but no water would come out. The water filter had been
changed recently, so I was fairly confident that it wasn't the source of the
problem, but removed it nonetheless.
(As an aside, the manual states that although it is recommended, the filter
is not necessary for the system to operate (but considering the difference
it makes in the taste of our water and ice, i wouldn't even think of not
using one!) and the filter is easily removed and replaced without having to
shut off the water at the wall valve.)
The system still failed to operate without the filter in place. Naturally i
then checked for good water flow at the line, and it was fine. Not knowing
what else to do, I called for a repair tech.
A repairman came out and disconnected all the lines, valves, etc. and could
find no problem. Yet when he reinstalled everything, the water flowed
normally! All he could say is there must have been a small blockage
somewhere in the line that resolved itself with his disturbance of the
system parts, and consequently charged us for a service call.
Fast-forward 1 year: the system suddenly stops working for the 2nd time.
Again, I had changed the filter about two month previously, so routine
maintenance wasn't suspect - but I removed it and emptied it out (you be
amazed at the black particles that come out, after only a month or 2!), and
tried the water dispenser - still nothing. Again, i disconnected the water
line and verified good flow.
I reconnected the water line and reinstalled the filter (which I had
emptied), and upon trying the water dispenser again I could hear water
flowing into the filter - and then stopping. This told me - and I think
this is a key point to check - that water was at least getting that far into
Determined not to call out the repair man again, I then went online
searching for a solution, and read somewhere that a user reported finding a
"frozen water tank" in his refrigerator's water system (make and model not
mentioned) which of course prevented his ice maker from working which he
subsequently determined was caused by a blockage. Suddenly it hit me:
Recently I had taken a beer from the fridge, and found it to be
slightly-frozen, which was unusual (we keep both the fridge and the freezer
temperature settings slightly colder than the "normal" mark.) I mentioned
this to my wife, and she remembered that she, too, had removed something
from the refrigerator section that was also frozen. Could it be that our
problem was as simple as a frozen water line, tank, etc?
Consequently, we removed everything from the freezer, placing the contents
temporarily into ice chests, and unplugged the refrigerator power cord.
Thirty minutes later, I reconnected the power and - whatddya know, the water
flowed! (Note: the fact that the repair technician had the power off for
about half an hour is no doubt what "fixed" the problem the first time, as
well; i.e., the ice blockage had time to thaw.)
I changed the thermostat setting of both the fridge and the freezer sections
to a "hair" on the warm side of normal, and I fully expect that this will
solve the problem.
