Client Reg No XIH 1301920 Date [protected] This product was purchased in Sept 2015 and has given no problem until recently when it started to become extremely noisy and vibrated a lot. The problem indicated faulty bearings and an appointment was arranged for the technician to visit (parts were covered but a call out charge would apply). He duly arrived on the appointed date and the problem was fixed in 10 minutes. The cause- the retaining bolts holding the counterweight had come loose which he stated should never have happened. The bolts had obviously not been torqued to the correct setting when leaving the factory and these had gradually worked loose. This could have caused irreparable damage to the machine through no fault of our own. This cost me £120 and I believe I should be entitled to a refund of some description. I appreciate there has to be a call out charge but the cost is a bit extravagant for 10 minutes. I cannot fault the Technician who was extremely courteous but felt a bit embarrassed by the situation.
