Wash Cycles Suddenly Taking Longer
Hi, my hoover hpb145 special edition 1400 is about 8 years old and the cycles have started taking longer, e.g. the fast 29 minute cycle takes about and hour and the 40 min cycle takes twice that! Is this a pcb fault? or is there a seperate timer in there? thanks in advance.

Hoover HPB145 Special Edition 1400 wash programmes taking much longer than normal
- The problem
- An 8-year-old Hoover HPB145 Special Edition 1400 began overrunning on multiple cycles with no fault code reported. The 29-minute programme was taking about an hour and a 40-minute programme roughly twice as long.
- Likely cause
- The strongest diagnosis in the discussion is a control/monitoring issue or an intermittent motor thermal overload cut-out operating during wash and then resetting after cooling. Another supported possibility is repeated failed load-balancing attempts before spin, which can extend programme time significantly. The exact cause was not confirmed.
- What fixed it
- Recommended action was to observe a full cycle and look for abnormal behaviour, especially long pauses or repeated unsuccessful attempts to spin and balance the load. If no balancing issue is seen, the accepted reply suggests the main PCB is a logical suspect, but no repair was confirmed.
- Checks to try
- Observed that several programmes were taking much longer than their stated times
- No error code was reported
- Advised to watch a cycle for long pauses or repeated unsuccessful spin/balance attempts
- Parts or tools mentioned
- main PCB
- motor thermal overload cut-out (TOC)
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

It's logical to suspect the main pcb when the programme starts to take much longer to complete but doesn't produce an error code. The pcb monitors everything and is supposed to produce error codes if any fault is detected. However, some faults do not trigger error codes on some washing machines. One possible cause is if the toc (thermal overload cut-out) in the motor cuts out during wash but resets itself after cooling down. It can cause the programme to stop but then start again when it cools down.
Other than that, one thing that could lengthen a programme is if the washing machine is struggling to balance the laundry prior to a spin. Some washing machines can spend ages faffing about trying to balance a load and it can really add a lot of time. You need to observe the washing machine throughout one of these programmes and see if you can see any strange behaviour that can account for it such as long periods and lots of unsucessful attempts to spin.
