Lazy spa was working perfectly went to switch it back on and now it wont go on

If your Cancun lazy spa is not heating past 38 degrees Celsius (100.4 degrees Fahrenheit), there could be several reasons for this issue. Here are some troubleshooting steps you can try to resolve the problem:

1. Check Water Circulation: Ensure that the water is circulating properly in the lazy spa. Make sure the water pump is functioning correctly and there are no blockages in the water flow.
2. Water Level: Check the water level in the lazy spa. If the water level is too low, it can affect the heating process. Ensure that the water level is above the minimum level required for proper heating.
3. Heater Unit: The heater unit may be malfunctioning or not working at its full capacity. Check for any error codes or indicators on the control panel. If there are error codes, consult the user manual to determine the issue.
4. Temperature Sensor: There might be a problem with the temperature sensor. If the sensor is not accurately reading the water temperature, it could prevent the lazy spa from heating properly. You might need to replace the temperature sensor if it's faulty.
5. Electrical Connections: Ensure that all electrical connections are secure and there are no loose wires. Faulty connections can lead to heating issues.
6. Power Supply: Make sure the lazy spa is receiving the correct power supply. It should be plugged into a dedicated power outlet that can handle the load required for heating the water.
7. Ambient Temperature: Cold weather can impact the ability of the lazy spa to heat up efficiently. If the outside temperature is significantly colder than the desired water temperature, the heater might struggle to maintain higher temperatures.
8. Thermal Blanket or Cover: Use a thermal blanket or cover designed for lazy spas to help retain heat. This can prevent heat loss and assist in maintaining the desired temperature.
9. Filters and Water Quality: Clean the filters and ensure the water is well-balanced and properly treated. Poor water quality can affect the heating process.
10. Timer Settings: Check the timer settings on the control panel. Sometimes, the spa might be set to a lower temperature or a timer might be restricting the heating.
11. Reset: Try resetting the lazy spa by turning it off, waiting for a few minutes, and then turning it back on. This can sometimes resolve minor issues.

Manoac lazy spa pump this beeing all the time soon as you switch it on all lights are flashing

E01 error code. Drained hot tub, unhooked green egg. Ran hose into the two filter pipes and back flushed the pump. Plugged back in and it works fine now.

is it a digtel type? or the analog type (turn knob)

The switch that is activated by the canister is your likely culprit based that it was working prior to emptying. Youtube has a quick video on this solution.

You probally just picked up enough dirt to clog the filter enough to shut the heater down. If the water flow slows enough the heater will boil the water inside it You have a presure switch in the heater to avoide this. All you probally have to do is clean the filter and baskets to get enough flow to start it again.
