The Thermo fan function is a great energy saver while giving magnificent baking results with the heat sources (heating elements) coming on less frequently to produce a even hot air flow in the oven.

Now the reason for this post is tell you more about the Thermo-fan in the oven and quick a way of spotting when fan is busy failing.

  • One of the many great features of the Thermo-oven is that you can bake on all the shelves and the baking result will be consisted. Once you start noticing different shades of brown on the cookies or the potato-bake is a bit sloppy on one-side, then you know the fan are no longer distributing the hot-air effectively and evenly 
  • The oven is getting hot but no air is blowing inside the oven or
  • The fan is blowing but it sounds like a Boeing is taking-off inside the oven 
  • If the oven-door are closing properly and the oven seal are not broken but the baking results aren't up to pare - then it could only be the fan becoming slower and weaker

Once the temperature start going haywire and the oven is playing up clients also start noticing that their oven doors aren't that hot. Don't worry about this it is just another great feature of the Defy 731 - it has a Air cooled oven door.

The Oven-door has little air-slots in the door that when the hot air starts to rise, it pulls cold air from the bottom though the double oven door glass. This constant flow of  fresh air  movement keep the door cool while keeping the hot-thermo-air inside.

I better stop raving about the Defy 731 stove because you might think I am getting paid for this post but it's just that I love with this simple looking stove with all her hidden features!

There is so much more I can tell you about  this amazing-beautiful-easy-to-operate-oven. Feel free to send me an e-mail and we can chat for hours about oven creations.

Happy Baking!

Drain Pumps

Appliance Repairs in Port Elizabeth. South Africa

Drain pumps are used in Washing Machines, Dishwashers, Ice-machines and other small domestic appliances to drain water out of appliances
Universal Drain Pump
There are many different types of Drain Pumps but the most common type that is used in Domestic appliances are the Induction motor and Magnetic Type

Induction Pump Motor

The main feature of this motor is that the impeller turns around in 360 degree circles to expel the water. (Impeller is the little blades in a rotating sharft that scoops water in a direction) This type of motor-action is ideal for a very powerful pump to drain water fast.
The negative 
Because this motor only turns in one direction it is so much easier for everyday articles like; hairpins, nails coins and curtain hooks to lodge themselves between the pump-blades. When the pump impeller cannot turn the motor overheats and burnout.

Magnetic Pump

This pump motor drains the laundry water by vibrating the impellers - there is no turning action. Its much harder for something to lodge inside the pump and impeller-blades because of this vibrating-action.
The Negative
The magnetic pump motor has a shorter operating life compare to the induction pump motor.

Signs of a Faulty Drain Pump Motor

  • Water left behind after completig washing cycle
  • Laundry is still wet after spinning
  • Water drain during rinse cycles but once it gets to finale rinse the pump is all heated up and then it does not want to drain.
Quick test;  Drop the outlet/drain-hose flat on the ground if water doesn't run out there is a blockage somewhere in the outlet system

If the water flows out freely then the pump is on the Blink
