Most systems allow for a length of the capillary tube from the filter to be fixed on the outside (or inside on some machines) of the return from the evaporator. This is done to improve the efficiency of the sealed system and keeps the return tube from forming condensation because it is colder than the surrounding air.
The automatic defrost operation is done simply by warming the evaporator area by means of a small heater unit. This melts the build-up of ice particles which run off the base of the unit into a catchment channel. Read the rest of this entry »
The humble kettle has been given a new image in recent years. Simple versions consisting of only a container with a heating element fixed inside are still available, but for many years the trend has been towards the automatic kettle that turns off once the water has boiled.
Some more recent models have been further improved with high-speed elements and spout filling. The latest jug version combines all the features of a modern kettle with the added feature of the handle’s being positioned on the side, so that the user avoids the steam when pouring.
As with irons, cable damage through wear and tear and misuse tends to be a common fault. Cordless kettles and jugs preempt this problem. They are similar to cordless irons in that they require a power base that has its own mains lead. When the cordless kettle is placed on its base, electrical contact is made to its heating element. The operation from then on is like any other automatic kettle. Read the rest of this entry »
For symptoms, possible causes and action relating to cylinder vacuums, see the Fault finder for upright vacuums. Unless the appliance has a power head attachment, references to the brush rolls can be ignored. Checking a long hose for blockages can be simply done by dropping a coin down one end, gradually lifting the hose and listening to the movement of the coin. If a blockage is present, the point at which the coin stops indicates the location. If the blockage is near either end of the hose, it may be necessary to remove the actual hose end if possible. In most instances, reversing the airflow through the hose frees the blockage. Read the rest of this entry »
