Siemens Wage Washer Problem Code E18

I reached out to Siemens Home Appliance Authorized Service after encountering an E18 error on my washing machine. The service technician charged me a whopping 300 TL, claiming that the machine's water pump was faulty and the replacement cost was 3,800 TL. Not being at home at the time and having my mother-in-law handle the situation, I instructed her not to proceed with any repairs. Upon returning home, I decided to investigate further. I opened the water pump section myself and cleared the blockage. To my surprise, I found a few coins and a small wrench inside. After reassembling the pump and hoses, I restarted the machine. Lo and behold, no E18 error or any other issues! It's running smoothly like clockwork. When I searched for the stock code of the pump online, it was priced at 500 TL. It seems that the Siemens service team is not only making a quick $300 but also attempting to deceive users by installing a 500 TL pump for an exorbitant $3,800, aiming for even more significant profits.
