How To Tell If A Dump Valve Is Bad July 05 2015, 2 Comments

Dump ValveAs part of our Troubleshooting Manitowoc Ice Machine Series, we will be visiting the water dump valve, found on almost every Manitowoc ice machine made. These valves are extremely common and only come in 2 different varieties. That's right, every dump valve on every Manitowoc ice machine is only 1 of 2 different parts, either 115v or 208-230v. This brief post will share the best way to diagnose the dump valve.

First, the two different dump valves are Manitowoc OEM part number 000001767 for 115v ice machines and 000001768 for 208-230v ice machines. We keep both ice machine parts in stock and are available for standard and rush order shipping. They are also very easy to change, almost anyone can swap out a dump valve on a Manitowoc or Koolaire ice machine.


Manitowoc Dump Valves - When to Change? September 18 2014, 3 Comments

Manitowoc dump valves come in only 2 different types, a 115v and a 208-230v.  This makes keeping a spare part on hand easier, limiting the amount of stock.  In addition, it makes it easy to know which ice machine part your maker needs, since we only need to identify if you have a 115v ice machine or a 208v machine.  But let's look at why it may be necessary to replace a dump valve on a Manitowoc.

Typically, a dump valve requires replacement if you have a blown fuse.  What happens is that the top of the valve will leak, causing an electrical short.  This blows the fuse on your control board and can only be fixed by replacing the dump valve.  A valve leaking bad enough to cause an electrical short will be obvious, as you will see water spurting from the top of the valve and usually a large amount of calcium build up.  The calcium build up will look similar to the corrosion on a battery terminal in your car.

Manitowoc Dump ValveWhen buying a dump valve for a Manitowoc Ice machine, there are only two choices. For all past and current ice maker models there are only 115v dump valves and 208-230v dump valves. This makes truck stock simple, allowing you to keep only 2 items in stock that will solve and fit all Manitowoc ice machines.

Typically the 115v dump valve will fit all 500lb cubers and smaller. The voltage change happens at 600lb machines and larger, which are then fitted with 208-230v dump valves. There are a few exceptions, like in the Ice Beverage model line up, which can produce 1000lbs of ice or more, but only have a 115v ice maker head. Be sure to look up the part number and voltage of your ice maker before ordering.
