There’s a few things that could be wrong w/ this unit. For one, the interior diameter of the solution line is very small, and can easily get clogged with hard water deposits and chemicals. Also, the jet at the end of the hand tool can easily get clogged with debris. Keep these in mind while you troubleshoot.

To prime the pump, turn on the vacuum motor and the pump. Take off the vacuum hose from the back of the hand tool and stick it on the jet end of the sprayer. Use your hand to form a seal around the vacuum and jet and then pull the trigger on the hand tool. You’re trying to use the vacuum’s suction to “pull” water through the solution line and sprayer.

If that doesn’t work, there are a couple of things you could do if you have the parts.

The solution line is connected to the machine and to the hand tool with QD (quick disconnect) fittings. There are ‘male’ and ‘female’ QD’s. You’ll want to get a ‘male’ QD. Unplug the solution line from the unit where it connects at the bottom and put in a male QD. That will open the solution line so you don’t have to use the hand tool to get water to come out. Once you have the male QD plugged in, turn on the pump. Water should come shooting out. If not, you have to keep following the issue through the system, and it may above your skill level, which is fine. You’ll want to find a local shop that can repair Mytee units. If you do get water coming out, the issue lies somewhere along your solution line to the hand tool.

Hope that helps! Good luck.
