If you're going to repair a major appliance, you need to disassemble it first. Obviously, the first thing to think of is doing the reverse of how the manufacturer built it. Always remember to leave the bits in an order so that you can put it back together.
How to disassemble and reassemble:
Start by removing the fasteners and knobs - these tend to be push-fit ones and can just be pulled off their positions. Alternatively, there will be clips, pins or screws for easy release. A good example is a washer. For this, the clips can be difficult to locate and you need to run a knife on the seam until there's an obstruction. Then push the blade directly into the clip and push up on the panel. Keep doing this until you can lift the panel off.
Find hiden fasteners - It's also possible that these may well be hidden in an unknown spot, like under a logo or nameplate. Just pry parts up and find the fastener. Remember was reassembling, to conceal the part back over.
Reassembling - Make sure that any lint and dust is vacuumed out from the inside of the appliance. Double check to make sure that adjustments and repairs are done well and there aren't any other problems. Always lubricate the motor if the appliance has one.
Reassembling is just the reverse of disassembling. Remember not to force the parts together or tighten the fasteners too much. Once you are happy with it, reconnect and turn on the appliance, any smells, overheating or noise and turn it off again before going over the repair process.
It can be difficult to find the best companies for appliance repair, but by repairing instead of replacing appliances, you tend to save a lot of money. Through not getting rid of appliances you save landfills and if you get them repaired by an expert you can avoid continuous costly repairs and keep your appliances top of the range. If you call an expert when trouble is first seen a lot of hassle and energy can be saved, and in some cases catastrophic failures have been seen by not taking that advice.
