My wiper motor is overloading and will not spin. What could cause this and how do I fix it?

There are three possible causes for an overload of the wiper motor: improper tension of the wiper blocks against the evaporator (SOP- Wiper Fix) corroded bearings in the transmission (SOP – Transmission) or an excessive amount of residue buildup in the evaporator (SOP – Clean). A quick phone call to Technical Support will get you started on the right path.

My transmission is leaking air when vacuum is applied to the system. What could cause this and how do I fix it?

The transmission is the metal cylinder on top of the wiper basket and creates a vacuum-tight seal between the rotor of the wiper and the rest of the system.

It is composed of two bearings and a few gaskets.

The bearings should be lubricated every 4-6 months with 0.5mL of white oil. If crude oil contains sulfur (usually from using sulfur burners in the grow to prevent powdery mildew) this sulfur can cause rapid degradation of both the gaskets and bearings in the transmission.

While the transmission can be easily rebuilt by following SOP- Transmission Fix, it is not recommended to process crude oil that contains sulfur.
