I have a portable air conditioner from dimplex, dac15hc, it cools when 1st turned on then aprox 1-2 min later i hear the compressor turn off, the air coming out gets warmer until a code of ES is shown on the screen, please help

Take it to a refrigeration engineer. It sounds like it is 'short cycling' and may need refrigerant gas. Also check the filter and condenser fins.

compressor trying to start but not starting replace capacitors.

This unit is a room AIR CONDITIONER, not a heat pump. It only cools, it won't generate heat.

if the sensors are okay, it might be the compressor overheating, my portable ac (moretti elite ac) is also behaving the same, especially when i turn the fan to max. the compressor shuts down about 7 mins and turns on again in about 5 mins, now i found out when i turn to medium or low the compressor runs normally. i think when on medium or low setting some of the cool air directs/channels to the compressor thus cooling it more.

Here is a manual for your portable air conditioner

Unfortunatley, you didn't mention which model you have. But if you click on the link below, you can locate your model and once you click on it, you will see a link to the Owner's Manual. You can download and print it for future reference.

I hope this helped you. Please let me know. Thanks.

Make sure the filter is clean and if it is it sounds like the fan motor stopped working.

well when u have outages the voltage drops obviously, the one that suffers are the capacitors the capacitor for the compressor might need to change, change it with the same capacity as the old one example if labels say 55 microfarady ( mf ) ( 55 mf ) get one of the same I am not saying it is a 55 mf capacitor vary depending on motor and brand. So check the label
