VPI - Final Tweak
If you do not get enough suction force from the first tweak, or the VPI is leaking water, then you have to do a thorough maintenance.
WARNING: Unplug all electricity input to your VPI machine before the task. Consult a certified electrician or employ his labour. The following can be a dangerous task and risky. And the pictures below may cause discomfort!
Detach the bottom cover of your VPI machine you would know that it is just a very simple machine. A running motor, a vaccum motor and a water filter does all the work. There are 2 pieces of sound absorbing material. In my case they are full of black mould as there happened a water leakage at the water filter.

Sound Absorbing Material
The water filter is the only place to have leakage. First take away the vaccum motor to a side. Then dismantle the steel-made water filter from the machine. Peel off all the old silicon gel. Re-apply silicon gel, use a lot of it!
After fixing the water filter to the box case, apply a very thick layer to seal off the outer-edges of the filter to make sure there can never be any leakage again.
Leave it dry for two days. This is a very important step. Remember, two days to make sure the thick silicon gel gets stable.
The vaccum motor can be rusty owing to moisture. Do not worry, use a sandpaper to brush the rust away. Then paint a thick layer of red oxide primer over it. This prevents the motor unit from rusty again.
The wooden board supporting the vaccum motor has become rotten in my case. Hence I cut a piece of arcylic board to replace it. This makes my machine somewhat 'water-proof'.
A capacitor is added to the electricity supply terminal to 'eat' the sparks created by the vaccum motor.
When everything has been dry affix the vaccum motor unit again. Note I have replaced the foam rubber to improve the contact between the motor unit and the water filter.

When you vac-dry you should now notice an increase of at least 30% power from your machine and it really roars with noise. Now I always wear a pair of industrial safety use ear-muff when washing my LPs with machine.
