Disappointing services from LG Cape Town

On 16 May 2018 I sent an email to LG Services saying I noted an “HE error” on my LG Dishwasher Direct drive D1452LF, Serial Number : 308KWBY2B205. Since the abbreviation HE means Heating Element, I requested that the heating element be replaced. Quotation was sent and payment of R1270 made. After some delay the element was replaced on 6 Jun 2018. Despite the element being replaced the dishwasher still shows “HE error”. Apparently “HE error” could mean a number of faults – unknown to me, the client. Should LG services/repairs not have informed me of this? The technician that installed the element was so kind and mentioned that this is an electronic/motherboard fault and not the heating element. I contacted LG services again. Another quote gets send to me on 18 June 2018: R600 for an assessment fee and field call! After that then only will the repair be done at what further cost? My LG experience in the past has been good. I had my washing mashine pump replace twice and all other appliances is LG. I am seriously disappointed at this level of service with my dishwasher and hope it can be resolved at no further cost to me, the client.
