when the pressure is high on filter mode it usually means that a backwash is required.
There wont be any dirt under the sand. When you vacuum your pool you should do it on filter mode Otherwise you will lose a lot of water for nothing, this would be especially wasteful in the case of a salt water pool. Ofter having vacuumed the pool on filter mode and if the pressure gets too high backwash. after backwash rinse for a minute, then return to filter.
Probably because it is clean, leave it on the filter setting for a while and you will find that the pressure will increase as the filter gets dirtier, when it get high (usually in the red ) you will have to backwash.
Backwash valve is leaking by. More than likely it is a bad oring inside the valve. Or it was not place back into recirc mode completely. or you may have a leak on the return side of the filter. That includes all the plumbing from the filter or heater to the pool. The back wash valve may be obvious if the waste line ends close by. The back wash valve should be placed in the "filter" mode not the "recirculation" mode. K

Filter-Basically the "normal" setting for your pump. Circulates water from pool to filter and back out again. Backwash-Your filter forms thousand of cages in which suspended particles passing through are caught. When these cages become saturated with dirt the filter must be clean through backwash and the dirt sent out. The pressure gague gives an indication of the pressure accumulated in the filter. Rinse-After backwashing a "rinse" operation is recommended before the filtration mode is restarted to ensure that no dirty water is returned to the pool. Recirculation- In this option the water from the pump will return straight to the pool without going through the filter. Rinse cycle is used to create greater circulation when adding chemicals during periods. Closed-As the name suggests, this closes off the entry of water to the filter and is most normally used when access to the pump pre-filter basket is required. Remember to always stop the pump before changing between any of these positions.

if your transmission has a modulator valve check the vacuum line to see if cracked if not change the valve if no valve change fluid filter and gasket that might do the trick
The sand could be sand from your filter. If you have aDE filter the screen could be misaligned. If you look and see if any water is coming out the backwash port while in filter mode the valve is bypassing. Does the pressure build up when you don't backwash for awhile? You might have a lateral broken inside the filter.
