We have an 06ish Fisher Parkel drawer dishwasher DS603i in my RV that decided to quit working over winter. Powers up, no problem. But the drawer will not lock into place as normal. I can hold the lock button and the lock light turns sold red, but I do not hear the normal noise when the drawer locks. I assume this is a permissive for the dishwasher to run as well.
I assume the latch mechanism is bad, but not sure. Has anyone else had this problem and resolved it?
Thompsdw, thank you for your question. This could potentially be a control or a lid actuator 522085 failure. To test this, voltage to the lid actuator motor would need to be tested for 24 Volts DC. If there is voltage present when the unit is activated, but the lid does not close, the actuator would need to be replaced.
Ok, thank you. So just so I am clear, I am looking to ensure that the actuator is powered when the power button is depressed (that is when it locks) by putting a voltmeter on the removed plug prongs? So, if it is powered then the actuator is likely bad? Does it make sense that 2 actuators would fail at the same time?
If not that, I assume you mean a bad control board? Can you give me the part number for that in case I need it?
Thanks for all the help!
It is very likely to be a main control issue. However, the control 528397HUSP for the model provided is discontinued and no longer available. To ensure it is not a happenstance that both actuators have failed, testing would be the best way to go.
Ok, so I went ahead and ordered the actuators because they were a free return on Amazon. The company send me a 519328P control board instead. OMG. That is kinda funny. There is NO chance that more recent control boards would work with my dishwasher? I will still do the actuator test prior! Could it potentially damage the new control board to try?
Unfortunately, the manufacturer does not show a compatible substitute for the control. There is always a chance that an incompatible control could be damaged when installed onto an appliance that has different components than what the control is rated for.
