You did not say what type of laundry you were drying,nor how full the machine was.
1. Heavy cottons and linen fabrics will take longer to dry then man made fibers. Especially with the low heat and air flow of 110v dryers. Unless the final spin is in excess of 1200rpms, count on one, to perhaps two hours to dry a "full" load.
2. Being as the above may, as you were already told, combination washer/dryer units are NOT the best dryers simply because of their design. Dryers normally have much larger drums than front loading washing machines of the same rated capacity, simply because larger drums provide for the air flow and movement required for heat and air to get at the laundry, fluff it and evaporate the moisture. With combination units, one either has to load the unit half or less full when using automatich "wash and dry", or take half or more of the laundry out of the machine before starting the drying process. If the machine is over loaded you will be drying items for hours and probably not even then get them totally dry.
3. Your post above is confusing, as you state the water was turned off, then you say you tried with the water on. Equator only made combination W&D units which used cold water (unvented), so you need to have water running into the machine. Keep in mind the unit requires "COLD" water, the colder the better as the difference in temperature between the hot air coming from the dryer, against the cold water is what causes the condensation which dries the laundry. If your area's cold water is above 86F, as it can be in some areas of the United States, during warmer times of the year and or warm weather, then drying times are going to be longer because you are actually using luke-warm to tepid water instead of cold.
All and all combination units are not the best thing since sliced bread they are promoted to be. Even in Europe, most consumer rating/guides suggest consumers if at all possible try for separate washers and dryers, and that is with 220v power heating the dryer.
Equator units have been plauged with problems for years now, though earlier models seemed to do their jobs reasonably well.
