Ive put new filters in my vegas spa but eo2 keeps coming on,any advice plse

EO Short circuit temperature sensor Er0, Er1 Temperature sensor fault Er2, Er3 High limit fault

test the motor frozen or damaged

looks like it's got a bad thermister or thermostat
E03 The pump's thermometer reads the water temperature below 4°C (40°F)
1. The water temperature is lower than 4°C (40°F).1. The spa is not designed to operate with water temperatures lower than 4?C (40°F). Please unplug the pump and move to a warmer ambient temperature. The pump should only be restarted when the water temperature reaches 6°C (43°F).

» 2. The pump's thermometer is broken.

If this is an outdoor spa near trees, its almost a guarantee that the impeller is blocked with debris (pine needles can cause this in a hurry)

If the impeller is clean of debris and this is still happening, replace you pressure/flow switch.

EO2 is a high limit code. If your flow is good then you should check the by-pass assembly in the water manifold on the side of the heater. Good luck

EO2 is a high limit code. If you have good flow to the heater you will need to check the by-pass assembly inside the water manifold on the side of the heater. All it means is the water inside the heater is getting too hot and probally not moving threw the heater fast enough. good luck.

Hi,
The reason for E02 seems to be that the water lines coming in (either hot, cold, or both) are either blocked or turned off. Basically the machine isn't getting any incoming water. Therefore cleaning out the filter might fix the issue.
