Though it's pretty well documented that you probably can't use a foam cannon with a Kranzle on a 15A circuit, there are certain times that the machine/plug/circuit will trip on a 20A circuit as well. This is very rare, but it can happen.
Electricity is a very fickle thing. We try to test and provide proven solutions, but there are still times when a certain pump may have a slight variation in the motor, or your electrical infrastructure is a bit inconsistent and we run into problems. If you're having this issue, here are some things to check:
1. How is your machine connected to power? Directly to the wall plug? Are you using an extension cord? Do NOT use an extension cord.
2. Are you using a standard water spigot and hose or do you have multiple hoses connected? Surprisingly multiple inlet hoses can have weird effects.
3. Have you checked your foam cannon for any blockages? See this article:
4. Ensure that your foam cannon has the 1.25mm orifice installed and not the 1.1mm. I'm not positive if your foam cannon came with both, but make sure its the larger of the two that you're using.
5. Even on a dedicated 20A circuit, some foam cannons can overwork the machine. You can try turning the red unloader valve down a bit to lower the pressure coming out of the machine when using the foam cannon. Or you can install a 1.5mm orifice in the foam cannon: MTM 1.5MM FOAM CANNON ORIFICE
