You are given the opportunity to choose from a list of faults that are common to your appliance. If you choose a fault, you will then be able to see detailed explanation of the symptoms that are common with that fault. If you can identify with the symptom/s, you will get the correct solution that will cover all possible causes of that fault.
So for example, if the fault is "machine not draining" the problem could be a faulty drain pump. Before you rush out to buy a drain pump, it would be wise to check for all other reasons why it may not drain, like blockages somewhere in the appliance or within your drainage system.
We hope from this you will see that buying a drain pump is a worse case scenario. A drain pump should be purchased only after all other likely causes have been checked. For the record, 9 out of 10 times the drain pump will be fine and the cause of the blockage will be a minor obstruction.
We advise on all the likely places where the obstruction is likely to be. If you choose the correct fault you will get the correct solution.
