Diagnosing A Manitowoc Water Pump January 22 2015, 4 Comments

Every commercial ice machine has a water pump, so Manitowoc ice makers are no different.  The water pump works by taking the water from the water trough, pushing up through the tubing, out and over the evaporator through the distribution tube.  It’s important for the water pump to be strong enough to push an even flow of water, but not too strong to cause the stream of water to miss cascading down the evaporator.  To troubleshoot a Manitowoc water pump, follow this guide for signs you may need a new ice machine part.

Water pumps consist of 2 main components, the motor and the impeller.  The motor turns, spinning the impeller, and sucking water out of the trough.  The force then pushes water to the top of the ice machine, which allows Manitowoc to make ice with a vertical evaporator.

Proper voltage must be supplied to the water pump for it to work efficiently.  If too low of voltage is supplied, the motor will not be strong enough to pump the water.  However, too high of voltage could cause the motor to burn up.  Checking to make sure you have the proper voltage at the ice machine is important for not only the water pump, but all electrical ice maker parts.

There are two main water pumps for Q Series and older Manitowoc ice makers, a 115v and a 208v version.  These 2 pumps will fit most any ice maker made 9 years and older.  However, please verify fitment before ordering or send us an email if you have any questions.
Most common Manitowoc water pump part numbers 7623063 115v Water Pump, 7626013 208-230v Manitowoc Water Pump.

Installing a new water pump requires the removal of a water flow clamp, if your machine is equipped with one.  This typically applies to under counter ice makers.  Depending on the type of water system your ice machine operates on, you will install the pump in 1 of 5 different ways.  However, each method is covered by the included components, along with instructions on how to do all 5 within the instructions.
On most ice makers it's a simple bolt in installation and the above listed components will not be required.  If the pump outlet tube doesn't quite line up, it's possible to rotate the assembly.  There are 3 screws located under the motor, which once removed will allow the pump base to rotate freely.  Once it's in the desired position, simply replace the 3 screws.
