Decide whether to repair or replace a washing machine that keeps breaking

It has broken down for the third time this year and the repair quote has arrived, but nobody has actually worked out if fixing it again makes sense or if you are just throwing money at a machine on its way out. This weighs the repair cost against replacement and its repair history, then gives a plain recommendation. For anyone standing in front of a dead washing machine holding a quote.

Your washing machine has broken down again and you need to decide whether it is worth repairing one more time or replacing it outright. State {MACHINE_AGE_AND_HISTORY}, meaning how old it is and what has gone wrong before, and {REPAIR_QUOTE}, meaning the cost quoted for this repair if you have one, otherwise a rough estimate. Weigh the repair cost against a realistic replacement cost for a similar machine, factor in how many times it has already needed fixing (a machine with a history of repeated faults is a worse bet even if this specific repair is cheap), and give a plain recommendation: repair or replace, with the reasoning in one or two sentences.
