As Qualin pointed out, FL's don't generally make a rule out of exploding randomly.
However, shoddy build quality and poor usage habits can manifest and CAN result in spectacular failure if you turn a blind ear to a roaring bearing or continuous out-of-balance/high-speed operation.
Poor usage habits may include any of the following:
~ Overloading
~ Inadequate detergent dosage/Too much detergent dosage
~ Excessive fabric softener usage
~ Frequent cold-water washing: Allows the buildup of mold/mildew/detergent scum*/bodily soils and oils, particularly in FL machines that are kept shut and/or are not run through cleaning cycles
*This and your own soil usually will degrade/corrode the metal supports and bearings in the washer - which will subsequently fail. PLEASE use hot enough water, with enough detergent so your machine remains clean! It doesn't matter whether the drum/door boot looks fine, its whats on the outside that counts!
If a poorly-built machine is respected and cared for, it can last a lot longer than if you just "use and abuse" the machine till it konks out.
(And before someone points out that FLs are rubbish because they require cleaning cycles - Regular hot washes, with enough detergent and/or Chlorine Bleach COMPLETELY alleviate the need to do so. Machines used in Hard-water areas that HAVE a heater in them should have a maintenance wash (HOT)with Citric Acid/Vinegar to remove buildup regularly and prolong element life)
