Breaks down - Company won't Repair

Our dishwasher quit working after 18 months.  After SIX phone calls to Fisher/Paykel, we finally had a repairman come out (contractor).  We paid him $95.00 to tell us the dishwasher was broke.
Even though we had an extended warranty, F/P refused to honor it saying the repairman stated that we had incorrectly loaded the dishwasher.  I find that hard to swallow as the repairman only viewed the EMPTY dishwasher. 
We were told we needed a new mother board and it would take 12 to 14 days to get the part from New Zealand.  After 3 weeks, the repairman showed up, opened the part and said "OOPS, they sent the wrong part".  According to F/P, it will now take another 2 weeks to get the replacement.  Then we will have to pay another $190.00 for the repair.  Customer service at F/P was RUDE and refused to expedite the part.
We give up.  We're going out tonight to purchase a different brand.  Don't waste your money on Fisher/Paykel.
