New Machine faulty/dead AGAIN in under 6 months!!

I am at my witts end with this defy washing machine. We bought the Defy Aquawave Technology DTL151 in November 2020. In December the PC board showed an error which the consultant I called didnt know so they sent a technician. He came and said the PÇ board was faulty and got a new one the following week. After connecting it, he realised it wasnt the pc board but the sensors that had an issue and went to get new ones which he installed a week later, upon installation, he realised it was the incorrect sensors and got the correct ones the week after that. We thought it was the end of that only to notice that the water would trickle into the machine even when it was off so we needed to switch off the tap behind it which wasnt a train smash, but that then meant the sensors weren't fully operational. We spent December and Jan with the technician coming in and out who wasnt very open when asked questions regarding the machine. And please note, we hardly use the machine as our helper prefers to handwash

Now we have the lockdown, it is the 5th time IN 2020 we are using the washing machine. I put a blanket and towel for a quick wash, go to the kitchen to wash the dishes and come back and the machine is quiet with the stuff trapped inside. I tried to switch it on, checked if the plugs were working only to find that it has just gone cold turkey!!! What on earth did you sell us! I cannot believe how unreliable this machine has been! We have so many relatively new defy appliances and if this is the quality of products you produce then we surely are regretting the purchase. You better send someone with a brand new machine because I am tired of your *********** technician that you send to do useless wor****! I also cannot believe that a machine purchased so late in the year can have so many faults! It hasn't even been 6 months! I am appalled! Lockdown or not, I want this sorted out immediately!!!!
