Meaco Dd8l dehumidifier fault light

My unit developed a fault just after the warranty expired. After less then a minute of turning it on the double fan light would flash, the fault light would come on and the unit would shut down.
After some research it would appear to be a common problem with this unit.

after stripping down the machine and inspecting it I noticed the dissident wheel was not turning. I removed the small electric motor, opened it up and re greased all the internal plastic cogs and re assembled, easy enough. Before re fitting motor I manually turned the dissident wheel and noticed it catching on something, preventing it from turning. On removal of the wheel I could clearly see the plastic case behind had melted and distorted. In the area directly behind the heater element. The dissident wheel has metal 'spokes' that literally brush past the plastic case behind.

i admit the unit has been turned off a couple of times before the unit has shut down properly and my guess is that the metal 'spokes' have stopped over the heater element and still hot element has heated through the spoke and melted the plastic behind, causing the distortion. Or this may be a design flaw, but was easily rectified by smoothing back down the plastic. On re assembly the unit worked like new.

fan @ compressor wont run,one light is flashing

flashing light is showing an error code. if the unit is under 5 years old it will be covered under warranty.. if you want you can try and reset the power by turning it off at the isolator next to your outdoor unit, leave it a couple of minutes and switch it back on. this will reset the fault code, if the flashing light comes back there is a definite problem, if it runs the fault may have been caused by a power surge or something

playstation3 wont turn on red flashing light then a double beep then turn off

Unplug the power cable from the back of the PS3, wait around 30 minutes...this will allow the unit to cool down. Plug the cable back in and try to boot the unit again. If you still have a red light, call PlayStation. If you're still under warranty, they'll send you a new unit at no cost to you. The problem may be the Hard Disk. This happened to me and PlayStation was very easy to deal with.
