Awesome days and cool nights!
Try Modesto Rodriguez in Boquete at 6657-4136. He's very good with all sort of appliances.
We had problems with our Samsung dishwasher. It was difficult to diagnose. It turned out to be the motherboard. Had to order from the US. We think the root cause was either an electrical surge or under/over voltages.
Before we got it fixed, we installed a whole house surge protector and voltage regulator. One can also buy individual devices to protect a single appliance.
We used Sr. d** **d and he was very difficult to work with.
