faulty lg wd8016c washing machine?

I have an LG WD8016C Front Loader Wasing Machine that is 4 years old and showing 3 faults: 1-Lately the door handle feels loose. It does not open anything.Door is always locked. Child Lock light shows on display until it turns off automatically.A friend told me that this handle uses a very small edge of soft plastic to lever up a relatively strong spring in order to open the door, indicating a very poor design.Could this be broken?What about the child lock light? 2- When washing the right amount of cloths (well under the max of 7.5kg) with hot water, together with the right front load powder (tried more than one) we get a large amount of foam and bubbles coming out from the top, bottom and front of the machine making using itcompletely unsafe. 3- While washing, display shows a time of 2.40 for ex., then it goes to 3.20, 1.50, 0.30, 2.55 etc. A complete nonsense. I believe these are all Manufacturers issues that they should deal with as it is well below its normal life expectancy.
