Is this a spring-wound timer?
You rotate the timer knob, and it begins ticking?

This type mechanical timer will work with any voltage.
What voltage line do you have?
240Volt has 2 hot wires. Connect 1 hot wire to timer. Timer turns off 1 hot wires, and that action will turn off 240V circuit.
120V has 1 hot wire. Connect this hot wire to timer, and it will turn off 120V circuit.

Be sure you have GFCI breaker or Arc fault breaker on spa circuit.

First, determine if the TV device is putting out sound by plugging in a headphone into the audio out of the TV. If audio is there then the
transmitter and wireless speakers system may be at fault.
You can also plug in a CD player playing a disc into the transmitter to see if that source then transmits the audio.

Usually this happens when you have a damaged power supply. Once you replace it everything goes back to normal. You can contact [email protected] for support on this.

Check for a bad heater controller board or burnt wire connection going to the heater. You can check for voltage across the white and black leads going to the heater from the heater controller board (upper left corner of the black control box

it sounds like the pump relay may be stuck closed. Also check the temp readout, if it thinks the water is too hot it will try to cool the water by running the jets and sometimes the blower as well.

The Fantasy has a drain located in the toekick of the spa. You have to first remove the drain cap, attach a hose if you wish, spin the outer black ring counter clockwise to start the water flow, then pull the outer ring out away from the tub to increase the drain to full flow.
I understand that a screw driver is often needed to pull the outer ring out to achieve full flow. Therefore, I suggest another method. Take a garden hose and place it in front of the jet while the spa jets are on. This will force water flow thru the hose and prime the hose. Once you see water running from the other end of the hose, drop the hose in front of the spa jet into the footwell and as long as the loose end is lower than the end in the footwell, a siphon will drain the spa as fast as the spa drain will. Remember to turn off electric to the spa once you have established a siphon. You may have to bucket the last bit of water in the footwell. Goodluck.

this may be for the ozone the other end maybe up toward the top maybe part of a double loop.hose is black or clear but with yellowish tint. this would only leak if the tub is off or clogged up filter, also during filling and draining. plug off hose and refill tub with water once full turn on. if this is for ozone it will draw air into line once you turn it on. if thats it need new check valve in line also.

I'm not familiar with this product but my guess would be that the wireless signal from the audio transmitter is either overriding the wireless in your room.

You might want to consider going to a bluetooth system. It's range is only 30 ft and it doesn't impact wi-fi equipment.
