We do not use our tub that often, but when we press the button it does not connect.

I have a old destiny river hot tub. The lights stopped working suddenly. I can hear a click every time I'm pressing the lights button. That probably means that a relay is clicking so the panel button is working well. But my question is do LEDs are connected in parallel or series? If series if one LED fails all of them will not work (good luck to find the bad one). Anyone have an idea?

Not exactly sure of your question?
If you pressed 'Light' button on topside control, do any lights come on, some lights, or No lights? Does the light 'Icon' come on, on the topside?
if there is an indicator on the topside that comes on when you press the appropriate button, then the communication between the topside and circuit board have been completed, and that action should work, in your case, the light should come on. If no indicator, that means circuit board received no communication to power the light (s). So... you hear a click? So do you also an indicator that lights should be on, if so - no lights are working, wire to light fixture is either unplugged, or light or lights are burned out, or bad wire connection.
if no indicator on topside control panel = Bad/dead light 'Button', which means bad panel - since you can't repair a button on a topside control panel.

Problem is too much soap. Wrong soap. Press and hold: SPIN SPEED & SOIL LEVEL buttons--then press POWER button.
Wait for door to lock.

Press the START button (6) times--this will fill the tub with hot water to the maximum setting when it stops filling.

Press the START button two more times--this will enable the tub to tumble.
After 3 hours--turn "off" the washer.
Turn the washer back "on".
Select the shortest wash cycle (usually "quick wash") and press "START". This will rinse out the tub.

IF that is the one I recall, the switch is not connected to the tub. When you press the button, it sends air pressure to the switch under the tub to activate it;. You need to check the tubing and the switch

Add the entire packet of "TIDE WASHING MACHINE CLEANER" directly into the tub (no laundry) and close the door.

This method of "TUB CLEAN" is *not* from a service manual but has been the best method for cleaning out LG washers more than a year into incorrect detergent usage.

After this--use the correct amount of "HE" detergent & perform a "TUB CLEAN" cycle every (4) months using the *tub clean* option on the control panel.

You might be using too much detergent and causing a sudslock condition. The machine uses very little water and any amount over a teaspoon of HE will simply cause the machine to lock down. An OE error means it took longer than 10 minutes to drain the tub. IF the machine is trying to correct a sud problem it will continually toss in more water till sudslock is corrected.

there might be a fuse at the pump that has blown

Most of the control buttons on a tub are not electrical. These buttons are connected to an air line that runs to the motor. Sometimes an aggressive button push can literally blow the air line right off of the bottom of the button.
This problem is as easy to fix as it sounds. Find the loose air line and push it back onto the button. You will need to open up your access panel. Bring a flashlight. Good luck

Contact the manufacturer for a replacement switch or go to a pool and spa store to match it up
