My sundance Marin spa displays all marks when you turn

Customer Question

My sundance Marin spa displays all hash marks when you turn the power on. It starts to cycle through the startup sequence for about 5 seconds before. Any ideas?

The 3 dashes are watch dog error code which usually means the sensors are bad. You will need to replace the High limit and thermostat sensors. I have seen this be a bad circuit board but that is not as common. Open the control box and find on the circuit board where the sensors plug in and trace wires back to sensors and replace.
