Hotpoint dishwasher problem- help please

dcGT

Hi All,
I have a problem with a Hotpoint SDW80 dishwasher. I'm getting an error code of AL05 intermittently. However the dishwasher has still been working over the past few weeks. Sometimes the error code appears at the end of the cycle and sometimes it doesn't. It's still washing and draining but there are some other issues:
1. When washing, the pump seems to start and stop a lot. Sometimes stops for a few minutes. This is a lot longer and more frequent than normal.
2. When the wash has finished, I switch the unit off by the power button on the front. However, when the door is closed and the unit is off (but plugged in), there is intermittent buzzing and clicking coming from the bottom of the dish washer.
I pulled the unit apart and it seems that the noise is coming from what looks to be a timer, from what I've found on the internet. There's a small circular piece that rotates inside the timer (linked to the timer motor, I assume). This keeps rotating randomly when whether the unit is on of off (but plugged in). This is what the clicking noise is. There seems to be 2 parts, the timer and the timer motor. Just a few questions: -
1. Would timer or the timer motor be at fault here (or something else)
2. If the timer is at fault, is it possible that there could be something that could be fixed inside it? I ask because the timers I found seem to be around €140 and I'd like to avoid that if at all possible. It seems to be around the same price again for the timer motor!

Has anyone any suggestions or is there anything I'm missing or anything else I need to check?

Any help would be great. Thanks!

if you think the wash pump is starting/stopping it is likely that the impellar of the pump is being obstructed from spinning freely and is cutting out on a thermal overload, check it for free movement or pull off a hose to check it,what you think is a timer is a diverter motor to change flow of the water
