How to solve it
If you think that the pump is the issue, you can try cleaning it or replacing the impeller.
b) Dirty or damaged filter
If the filter is dirty or damaged, it can restrict water flow.
How it happens
Over time, dirt and debris can build up in the filter, restricting water flow. If the filter is damaged, it can also restrict water flow.
How to solve it
The best way to solve this issue is to clean or replace the filter. You can clean the filter by backwashing it or using a filter cleaner. If the filter is damaged, you will need to replace it.
c) Blocked or broken jets
If they are blocked or broken, it can restrict water flow.
How it happens
Over time, dirt and debris can build up in the jets, which can restrict water flow. Additionally, if the jets are damaged, they can limit water flow.
How to solve it
The best way to solve this issue is to clean or replace the jets. You can clean the jets by using a jet cleaner. If the jets are damaged, you will need to replace them.
d) Airlock
If there is an airlock in the system, it can restrict water flow.
How it happens
An airlock can occur if there is air in the system. This can occur if the system is not vented correctly.
How to solve it
The best way to solve this issue is to vent the system. You can do this by opening the air bleeder valve.
e) Blocked or worn out ozonator
If the Ozonator is blocked or worn out, it can restrict water flow.
How it happens
Over time, the Ozonator can become blocked with dirt and debris. Additionally, if the Ozonator is worn out, it can restrict water flow.
How to solve it
The best way to solve this issue is to clean or replace the Ozonator. You can clean the Ozonator by using an Ozonator cleaner. If the Ozonator is worn out, you will need to replace it.
f) Low water level
If the water level in the hot tub is low, it can restrict water flow.
How it happens
The water level can become low for various reasons, but the most common is evaporation.
How to solve it
The best way to solve this issue is to add water to the hot tub. You can do this by using a hose or a bucket.
Issue 2: Hot tub pump is dead
How it happens
There are a few different ways that a pump can die, but the most common is a failure of the motor.
How to solve it

How to solve it
The best way to solve this issue is to replace the bearings. You can do this by following the instructions in your owner’s manual or by contacting a professional.
b) Scale deposits
If there are scale deposits in the pump, it can cause the pump to make noise.
How it happens
Scale can build up in the pump over time. This can occur if the water is hard.
How to solve it
The best way to solve this issue is to use a descaler. You can find these at most hardware stores.
c) Air in the pump lines
If there is air in the pump lines, it can cause the pump to make noise.
How it happens
Air can get into the pump lines if the system is not vented correctly.
How to solve it
The best way to solve this issue is to vent the system. You can do this by opening the air bleeder valve.
Issue 4: Water gets hot, cold, hot again
How it happens
This issue can occur if the thermostat is not working correctly.
How to solve it
The best way to solve this issue is to replace the thermostat. You can do this by following the instructions in your owner’s manual or by contacting a professional.
Issue 5: Control panel shows an error code
a) OH
If the control panel shows the OH error code, the water is too hot.
How it happens
This can occur if the thermostat is not working correctly.
How to solve it
The best way to solve this issue is to replace the thermostat.
b) COOL or COLD
If the control panel shows the COOL or COLD error code, the water is too cold.
How it happens
This can occur if the thermostat is not working correctly.
How to solve it
The best way to solve this issue is to replace the thermostat.
c) FLO or FLC
If the control panel shows the FLO or FLC error code, there is a flow issue.
How it happens
A few different things can cause a flow issue, but the most common is a malfunction ing pump.
How to solve it
The best way to solve this issue is to replace the pump.
d) DR or DRY
If the control panel shows the DR or DRY error code, the hot tub is dry.
How it happens
This can occur if the water level is too low.
How to solve it
The best way to solve this issue is to add water to the hot tub. You can do this by using a hose or a bucket.
e) SNA or SNB
If the control panel shows the SNA or SNB error code, there is a sensor issue.
How it happens
A few different things can cause a sensor issue, but the most common is a bad connection.
