Before You Buy A Dump Valve

Before you buy a dump valve for a Manitowoc ice machine, make sure to verify the voltage.  While model numbers are 99% effective at giving you the information you need to find out the voltage, some machines can be special ordered in non common voltages.

Did you know that you can order a 300lb Manitowoc cuber in 208-230v?  It would be very rare, but these machines do exist, so it never hurts to check your voltage before ordering.  This same rule would apply to components like water pumps and inlet valves.

Manitowoc Water Pump Problems

Manitowoc water pumps are another commonly replaced item on an ice machine.  Over time they can either lock up or, as hard as it is to believe, gain strength.  What can happen is the pump will eventually increase in power, forcing water too fast through the distribution tube.

When water comes out of the distribution tube too fast, it does not allow the water to cascade down the evaporator, instead splashes over the water curtain. Ice will not form properly or efficiently when this happens, luckily there are 2 ways to fix this issue.

The first fix is to simply apply a clamp to the molded tubing running from the water pump to the distribution tube. This will slow the water flow and allow the water to exit the distribution tube properly. Another option is to simply replace the water pump.

Most Q Series Manitowoc ice makers and older use only 2 different pumps. There is a 115v water pump and a 208-230v water pump, that will work in most cases. If you have an S Series Manitowoc ice maker then your water pump will be different, depending on which model number you have. You can purchase both pumps for just $222.18 from IceMakerPartsShop.com
